Thanks a lot for your honest feedback, it's very much appreciated! (I also had a very brief look at your Winter Weather Game, it looks very good. Let's just say I feel honored by your comparison.)
You're right, I crammed way too many mechanics into that game and in the end I didn't explain any of them properly. Teaching mechanics to players is something I still struggle with. Also thanks for pointing out the dissonance between some of the mechanics and the overall atmosphere. This is something I would never have noticed by myself.
I greatly underestimated the effort that goes into making 3D levels. I think I'll treat this as a learning experience and stick to 2D games for now, but thank you for your suggestions!
