Nice entry, I did like the idea! The main problem for me is that the game looks somewhat unfinished, or not polished enough. If I could give you a piece of advice, I'd say: make a smaller game! And save time for graphics, animations, better collisions, complete gameplay loop, etc. Sometimes in game jams, less is more. It's still really cool you managed to make all of this, but it would be even better if your work was forming a complete, cohesive game--even small. Nice work here, keep going!
