A few comments from me:
1. Awesome!
2. Mission 2 ending has a weird glitch. I get the cool sequence where the turrets are all firing at me and there's the cool slow-mo sequence but after it, I die even though I cleared all the turrets, and the level resets without letting me continue to the exit... except if I go to mission select I can start mission 3 so I apparently completed mission 2 by dying?
3. After the climb up the tower of beam turrets near the start of mission 3, sometimes the platform you land on isn't wide enough, and dodging will make you step off the side and fall off the map... Hitting a checkpoint after doing so causes parts of the map not to load in properly, which makes it look even crazier than it already does.
4. Have I mentioned "awesome" yet? Because AWESOME!
