Sorry to hear that you didn't find it that fun. Hope you still got something out of it. I got some good feedback from watching you play it on stream so thanks for that. It helps a lot when designing future games :)
Seemed like you spent more time on the art than on designing a fun gameplay, thats all. For gamejams i think its a good idea to focus on design for the majority of time and then polish up the experience a little. But thats just my opinion :D
