This is really cool!
I love the level of ambition in this project.
The mechanics have a pretty cool concept to them, and I like that you also paired your alternate projectile as a teleporter!
My only complaint is that the controls feel a bit too clunky (there's too much lag time from when you press the button to when the action occurs), and movement feels floaty at times (takes too long to stop when you either get hit or deal damage)
Other than that, I think this is a very solid game. Nicely done. :)
