It's really a great achievement and you can definitely be proud of your submission. I know that creating assets AND do all the programming in just a short weekend jam is a great challenge. It's very impressive when people join this jam and go fully solo. :)
You concept is solid and the game is actually fully playable. Like, the basic gameplay is working! So yeah, really good job! If you update it further, let us know. I would like to play the finished version!
