I got to the green level with two cross shapes. Bookmarked this, I will likely pick this up again tomorrow when I'm less fatigued. This is definitely one of the top games in the jam, the project was scoped well, no part of it is overdone and the minimalistic graphics allowed the development (and thus the player) to focus on the gameplay and level design. The difficulty ramps up well from what I can see so far. I think this is of a quality where it could be published on Steam for example.
Please stop by my Gameoff entry and give it a rating too!
