After another 5-6 hours I got the basic prototype working.

So I’ve already got the level layout done, enemy ai/movement/etc. (still missing 2 more enemy types though), player movement and interaction, score and life system and some other minor stuff.
But I’m still missing the evolvement mechanic for the player which is going to be a lot of work. Also I still have to do the menu and sound/music. I think I’ll do that tomorrow.

Seeing all the other blog entries is kind of intimidating. There are lots of cool ideas out there and other devs are making great progress.
I also fear that I interpreted the “evolvement” a bit too loose. Right now it’s more like leveling up than evolving, but this was the best idea that I could come up with.
