Wow, I think that's the most complete, polished solo monthly game jam I've played! Well done, really excellent! I think you should seriously think about making this mobile compatible - I think it'd be a great fit as a puzzle game.
First of all, you did a lot with polish from sound effects, eyes moving around, a nice menu, story, slowing down when coming close to another color, etc. And achievements! Well done!
The game was fun! Good puzzle elements, as well as some skill involved to sling the CoBa's and plan it out.
The little CoBa's were charming and the sound effects worked well.
Level design & tutorials were really good. Some challenging levels but some appropriate tutorials in the beginning.
I think the one thing the one bit of critical feedback I'd have is the narrative was a bit confusing? I wasn't quite sure what was going on haha (admittedly, I haven't finished the game). Didn't detract though since the gameplay is fun in its own right.
Two requests: LMB to continue through dialogue, and level selection so I can pick up where I left off!
