32k required From the author: It's inspired by a game I had for my CPC 464 called Bounder (no need to post a video in this thread, I'm sure anyone can find it on YouTube ), and it fits very well to the capabilities of the TI-99/4A. For now only the scrolling background and the basic jumping of the ball is working. The plan is that you should be able to pick up the spinning coins, while the question marks will give you a random 'power-up'. You will die if you land in water and if you try to jump over lava. The arrow will trigger a super long jump. The key features are:

• Smooth bitmap mode scrolling, but slow in order to save the CPU for gameplay and music.
• Character patterns are uploaded from CPU RAM on the fly, but double buffered, allowing the screen to scroll every 6th frame.
• A constant, slow scroll speed allows the patterns to be animated while they scroll.
• Runs with 3 pattern tables and 1 color table to avoid problems with more than 8 sprites in half-bitmap mode.
• Map is stored as meta-tiles (2x2 characters) to save space (the map in the preview only takes up 1KB as meta tiles).
• Meta tiles also reduce the number of character transitions in the map, which is important for the scrolling. Any combination of the 7 meta tiles is possible using a maximum of 112 characters, but the preview actually only uses 64 characters.
