Impressive work. Very enjoyable action packed gameplay. I really liked all the visual effects and the variety of enemies. It gets tricky when it's only you (speedster) vs one (speedster) since it looks like they can't damage each other, so you have to swap untill the new spawned enemy gets near your old exploding one. The game is very well made though and super fun especially when playing with the big guys later on.
Excellent game overall. Well done!
