Wow, usually jam games are cute and little bu not very polished, but yours actually feels like a game I could have found out there on the internet already! I love graphics and ambience music, the gameplay is a bit on the hard side for my personal taste, but I guess somebody more used to action-packed games would feel at home here. I see a lot of room for new features (weapons, new stuff falling down, ...) so you should definitely keep it up as something very complete and satisfactory can come out of this prototype! Well done!
