Nice visuals. Unfortunately, I got stuck on the door right before the first mini-boss. I was confused on the fact that I was picking up the 1’s…maybe pressing E or something would help with that. The core of the game seems fun overall, and your enemies/character are cool. Might be cool to update your thumbnail with the character’s face with that distorted effect on it.
EDIT: went back and played some more. Core gameplay is pretty good. The gun vastly outpowers the sword though. It’s cool you can deflect bullets with the sword, so maybe level 2 should focus on that more…or maybe you have certain rooms that focus on that? I definitely wanted more reach with the sword though. Also, picking up the 1’s one-by-one (ha) is fairly tedious…maybe you can just show a counter for them and “collect” them with an action like mentioned above.
