My attempt to push the 48k ZX Spectrum to its limits.

Keys O,P,M. TAP file is here if you want to run it on an emulator/real hardware. It'll need an original Sinclair machine (48k, 128k, +2), it probably won't work on Amstrad, Pentagon etc. clones, but if someone wants to mod the source to support them that'd be cool.

It's Mario style gameplay, find all the keys to open the next parts of the game.

100 pieces of battenberg collected = an extra life. Bouncing on an enemy = +5, key = +40, breaking box with your head = +10.

You can jump on any enemy which isn't spiky, holding down jump while landing on an enemy will make you bounce higher.

I made a video about how I made this game: https://youtu.be/X5T3QWbFdPg

I want to do a port of Great Giana next, then finally a version of Sonic. I'm also working on Gameboy and Amiga titles.

I've also started a coding guide for the ZX Spectrum on the same patreon page if you want to learn how it's done (it's free). Source code to this game is also on there.
