I love the idea here. I think you've made good use of the theme, come up with a mechanic that is simple and intuitive, and managed to build a unique and addicting game around it. The keyword here is "addicting"- honestly the game itself is so much fun (I'm about to go back to play it some more). The simple, shape-based graphics are effective and suit the game well. The music is engaging, yet not distracting, and again perfectly matches the rest of the game. I've got to say this is my favourite game of the jam hands down (and there have been some great games for sure). Definitely gonna follow you and hope you develop this more and possibly consider an Android release. Fantastic work!
