Entertaining premise! I was not a fan of the tutorial being non-skippable, but not too big of a deal. I really thought the controls and set design were extremely well polished. The two gripes I have are the graphics not being very illustrative (like the obstacle in level 1 gives no indication that you need to wait through an animation before shooting again) and the enemies in level 2 are overly relentless. The invincibility frames on the enemies being removed might send this game from "pretty good" to "great"
