It took me 5 attempts to beat the AI, and I had a lot of fun along the way. I found the default AI well balanced. The controls seemed the right amount of frustrating. I imagine this would be a lot of fun in two player mode.
My fingers kept going back to WASD on their own and cost me a few games, but you were just following a different country's keyboard layout. I'll try to support AZERTY keyboards in my next game.
I enjoyed the art and sound and overall the experience seemed nicely polished.
