Lack of main menu music is odd. The text is all Engrish. There should be a health bar on the character itself, not just the top-left of the screen. I died 20 seconds after being swarmed by the green guys. Enemies should spawn off-screen where you can't see it happen. The in-game character art is better than the portraits, which make it look like a patreon erotic game.
Overall it's a mediocre Survivors clone. I'd say the music and presentation are the strongest parts.
