Good gameplay, cool graphics and sound.
The controls are a bit uncomfortable - I think that arrows, numbers and mouse combine poorly. Maybe it is better to transfer the control to WASD. Mechanics are intuitive, enemies are cool. Good job!
The game had WASD controls already since the beginning since I, myself, don't like arrow keys for movement. Thank you for playig!
I tried to use WASD, it didn't worked =(
May I ask what type of keyboard are you using to play the game?
Yes, I use QWERTY keyboard. I checked your game again now and the WASD control works. Maybe it was a bug of web page.
