the art, music and vibe is very good. Controls are alright, i think my main issue was that reading the text in browser requires a lot of effort and you dont have time for that.
Maybe another font, some extra shading or bigger text could help that?
For me it made the game not really feel out of control, but just more stressful i think. Especially the game over screen had really small text, that i couldnt really read sadly.
