what was your development process for making this game?


Well.. I wanted to create something like a bitmap mode game for VIC-20 (VIC does not have a real bitmap mode) and I'm a fan of Cauldron II game.
Just tested my drawing routines and added few software sprites. No design plans. :D

Thanks Misfit, it looks very nice. Did you write it in BASIC or in a machine-code monitor on a real VIC, or maybe in assembly on a modern computer and cross-assemble it?

I'm getting my old VIC-20 up and running - just need a monitor cable - and I'd like to try developing on it like I did when I was a kid. Although I imagine cross-development with an emulator would be more comfortable.


I use CC65 (for VIC-20, Atari, C64 etc.), z88dk (for zx-spectrum, Amstrad, MSX, etc.) C-compilers and emulators. Very decent and easy way to develop new software for old 8-bit machines.
