Fun game! My biggest improvement suggestion is adding something other than right mouse click to shoot (I have a laptop without mouse and right clicking is really hard, I usually use control-click as a right click, but that didn't work in your game for some reason).

Other than that, the small text looks a bit blurry at first (though I guess it's just a glow, but I would probably prefer it without glow). Also agree with some other commenter on the player movement feeling a bit floaty.

I really like the "go over there to start the game" mechanic as well as the particle effects and how you explained everything with some strategic text in the first level.

Cool concept! I like how you interpreted the theme here, lots of room for awesome level designs!

Although I had trouble dealing with the turret enemies and the player's movements, I still had a good time clearing all three of the levels in the game. Too bad I didn't get to see the "The End" text at the end, though; the turret enemies were killing me repeatedly off-screen. 

Cool game, got softlocked entering the 3rd level sadly

The movement feels very floaty, and the background rotating was really distracting. other than that, i enjoyed it : )
