The cublet was so CUTE!! The visual language was clear, well done sticking to theme and great job in the level design.
What can level up this game to ship would be playing around with different projections. The isometric view + orthographic camera is bit hard to work with a movement + mouse drag controller. FWIW, we also made a puzzle navigation mechanic, and struggled with similar issues.. you can try our game to see where we landed. :D
