This game is great! At first I didn't think it could really yield cool gameplay but you definitely proved me wrong by introducing the enemies, teleports and recharging-things. I like how even though you have all the time in the world to plan out your moves, it still feels like there is a lot of action going on when you move close to enemies because you can't let go of that button until you get to where you need to. The only thing I would add is a way to be able to tell which portal teleports to which other one when there are several.
5/5 all around!
