Good concept but lacks polish. Firstly I'd say that the boss could use a stun mechanism to evade it due to only shot death. Secondly very buggy, whenever you go through the white portal the screen gets stuck with the music on loop preventing me to progress onto the next level, also the every time you die I would be stuck on a black screen & had to spam space-bar & enter. The settings even though you would set the display to your desired resolution it forces back on 1280x1440p, same goes for the mouse sensitivity, it resets all the way to max. Other than that I'd say not bad for a first game from a small developer.
