Well made game. I like the graphics. I like the way you made goals that get more difficult as you go on. I failed the first few times not understanding what is going on because the instructions were unclear. Once I realized that I had to get the exactly correct value for healing, it made sense what the game was about and became more fun. The sound is pretty good. The way things move are pretty satisfying. Deletion felt wrong and it wasn't immediately obvious what the energy costs were. Solid.
