Also, I forgot to mention the current controls in the game:
W - move forward (in camera direction) AD - rotate camera Shift - Use special ability (Speedup OR spikes)
Reminds me of the good old Rogue Soul flash games. The keybinds were quite confusing though - I often pressed something else than I wanted and I got somewhat used to them after quite a lot of time (combined both keyboard and mouse controls because using only one of these was too hard for me). The take on the theme and the gameplay itself are fun on the other hand.
The concept is very fun! The controls were a pain in the ass, which was probably intended to be, but the need for 2 mice makes it limiting (using a touchpad made it an even bigger suffering). Making movement more difficult after each level (i.e. by adding camera/movement arrow "dizziness" ) would add more spice to it. Good overall!
