TLDR: Fun, simple but beautiful art, pleasant audio, and got me hooked for a long time.
The game has a great idea, its simple but addicting and allows for a great number of levels to be created with this base, the scenery music is fun and goes nicely with the game style. The audio FX was great and the best part of the gameplay the challenge at the end for not killing anyone, I tried and failed, it definitely brings some difficulty into the table, well done!
