Good level design, love the UI design and the message log. Good tutorial, great that you can rebind keys. Turning up and down has a different animation that turning left or right (I think) and it feels a bit weird. Gameplay is good, but movement is a bit sticky, making evasion difficult. The waiting mechanic feels like a debug cheat, and I think the solution would be to make there be "charge points" or many more batteries.
Here are some less structured thoughts:
The barrier mechanic is cool. There is no UI for different sort of attacks, so I'm not sure what that's for. The environment makes it easy to get lost, but surprisingly I didn't.
