Bleh, accidentally deleted my comment!
In short, fab original puzzle concept and super presentation with that comedic intro! Head-boppin' music too! Love love!
Maybe the dual wasd arrow keys controls were a little unclear at the start. I liked your in-game control tutorial pictures but perhaps arrow keys could be a little visually clearer. Luckily I figured it out after only a few explosions!
Please develop this into a full release, it has a lot of potential!
Looking forward to seeing more from you in future!
