This is really creative. The pause mechanic I found especially clever. I think the game could have used some more difficult levels, though---I never felt particularly challenged or puzzled by any of them. Good work on this!
Thank you so much for your feedback! Our idea was in fact to show the potential of the game, without blocking the player with real challenges in this first prototype. Anyway we are programming lots of expansions, even in difficulty, in the upgraded version of the product! Stay tuned if you like :D
