+atari2600land Posted July 8, 2017 Share Posted July 8, 2017 For those that don't follow my blog, I've begun work on an Odyssey 2 puzzle game inspired by Chu Chu Rocket called, well, you know. The object of the game is to complete all the levels. I have a first level done here. If you beat it, that's pretty much the end, the lines will turn to garbage and an unplayable level will present itself because I haven't programmed anything after level 1. Use the joystick to move the up tile. If the cat or mouse touch the tile, they will go in the direction it's pointing (in this case, up.) Otherwise, once they hit a wall, they will move right. To start the motion when you think the tile is in the right spot, press the Action button. Don't let the mouse touch the cat, though. Otherwise, you'll go back to the placing the tile part of the level. Anyway, let me know what you think. mouse9a.bin 1 Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted July 12, 2017 Author Share Posted July 12, 2017 Here's a YouTube video I made of the game. Quote Link to comment Share on other sites More sharing options...
LoTonah Posted July 29, 2017 Share Posted July 29, 2017 Looks interesting...never played Chu Chu Rocket, so this is new to me. What's next for it? Any planned game mechanics that we don't see here? What levels do you have planned? Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted July 29, 2017 Author Share Posted July 29, 2017 I have been so busy working on the Secret Government Waffle Project that I kinda forgot about this. I'll get back to it soon. I just design levels and put them in as I go along. Quote Link to comment Share on other sites More sharing options...
jimj Posted August 12, 2017 Share Posted August 12, 2017 Looks like a fun concept, I'll have to find some time to try out your ROM. I had never heard of Chu Chu Rocket, I'm going to have to try that game too. Seems similar to the play mechanics of Ricochet Robots, which is a fun board game.

+atari2600land Posted August 13, 2017 Author Share Posted August 13, 2017 Added some stuff: + mouse and cat make "thud" sound when running into a wall. + when level completed, game goes back to select screen. + added fifth maze. mouse15.bin Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted October 5, 2017 Author Share Posted October 5, 2017 Added new stuff: + You now have to press 01-07 to go to mazes. I did this because I plan to have more than 9 mazes in the game. + Changed "end" to a piece of cheese. + Refined cat and mouse collision code. (For those of you without a Dreamcast, "Chu Chu Rocket" is also available on the GBA.) mouse17.bin Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted October 7, 2017 Author Share Posted October 7, 2017 I changed the name of the game to Cat vs. Rat. Why? So it could be displayed on the title screen. I also added an 8th puzzle and refined the cat and mouse collision code some more. Press Action on the title screen to go to the puzzle selection screen. I have about 300 bytes left to put mazes in. My goal is for 20 mazes, but I don't know if I have enough room for that many. I suppose I could make it 4k, but I don't know if I will or not. mouse21.bin 1 Quote Link to comment Share on other sites More sharing options...
jimj Posted October 16, 2017 Share Posted October 16, 2017 In 2.1 the rat and cat collision doesn't work (at least not all the time), the mouse and cat go right through each other. This collision detection worked in 1.7. I'm playing this on a real Odyssey 2 if that matters. It's possible for the rat to be stuck in an infinite loop, but maybe this is only because the collission detection isn't working? I think you mentioned in your blog an option to press the action button or another button to restart the maze. If that gets implemented that would solve this problem. It's a fun little logic game as is, but if you wanted to add some competitiveness/replayability you could either add a timer that counts up to see how long it takes you to solve a maze or a timer that counts down (for example you must get the cheese in 30 seconds or you lose). With the second option you could have different difficulty levels (like level 1 gives you 30 seconds/maze, 2 = 45 seconds, etc.). Lastly, instead of picking the mazes having them play in a random order one after another would help to keep the game moving and keep you guessing a little more on how to solve the next maze (especially coupled with a timer). Then it'd be a competition to see if you could solve all the mazes in a row. Maybe save the toughest maze to always/only be the last maze like a boss ending. Of course I've never programmed an O2 game, so I have no idea how difficult it'd be to implement any of those ideas. As I said before it's fun as is, but after beating all the levels once there's not much incentive to come back and do it again (although in my old age if I wait a couple months they'll probably all seem new to me again .

+atari2600land Posted October 17, 2017 Author Share Posted October 17, 2017 Thanks for telling me about the collisions not working. I took some time and made the collisions between the cat and rat work again. Let me know what you think. mouse25.bin 1 Quote Link to comment Share on other sites More sharing options...
jimj Posted October 22, 2017 Share Posted October 22, 2017 (edited) Thanks for telling me about the collisions not working. I took some time and made the collisions between the cat and rat work again. Let me know what you think. Collisions work now, so does the action button to restart the level. Thanks again for making this, I enjoy logic/puzzle games. Edited October 22, 2017 by jimj Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted December 9, 2017 Author Share Posted December 9, 2017 I am working on this again. I added my new intro for games I make on the Odyssey 2 and added an 11th maze. For the longest time, it wanted to make the T in CAT VS. RAT a +, but I think I fixed that. I don't know how. Tested and works on real hardware. mouse27a.bin Quote Link to comment Share on other sites More sharing options...
majestyx Posted January 3, 2018 Share Posted January 3, 2018 This is a really neat puzzle game that plays well to the Odyssey²'s limitations... or should I say knack for games that contain mazes! Regardless, it's again cool to see non-standard characters being used for game graphics and I could see this being an ongoing title with more mazes as you come up with ones that work. Thanks again for another cool title for this platform! Quote Link to comment Share on other sites More sharing options...
