Pretty fun little demo! The graphics were definitely very simple and the tank controls took a bit of getting used to, but overall it worked pretty well. The laser was definitely the more fun weapon to use - swinging it around to swipe enemies almost felt like a bit of a physics-based melee combat simulator. I actually found it easier to play with both abilities turned on, since the slower player was easier to control (and it was easier to hit things with the laser). Good job!
