First day’s progress
End of day 1, and I’m doing pretty well. The game’s engine is pretty much done, including the dumbest enemies ever created, and tomorrow I’ll work on the level design. I’ve made a start on some tiles and sprites:

And while I’m happy with the tiles, the sprites are rubbish. It’s a pity I don’t have time to redo them properly.
Anyway, I’ll keep going in the morning.
