It took a while to understand what was going on. A tower defense where you inflict bad luck on the attackers is a fun approach. Here are my recommendations with the general playability as well as teaching info to the player:
- Have the nut sprites in the stash disappear whenever enemies reach it, so you know how many are left. It seems this is the eventual intention with it.
- It might help if the build spaces have like a dotted square blink over them a few times at the start of the level, just to hint on where the build spaces are.
- Most importantly, I think this game would benefit from idle time before waves, like 10 seconds to start setting up your defenses. Right now, the third level starts instantly and you have no time to think about how you want to defend your zone.
Overall, it's a cool project. Handles the Game Boy look very nicely.
