I would basically just repeat the feedback that you already got, but my main issue was that the enemies dealt way too much damage for such high speed and comming from off-screen fashion. Feels really unfair for the player and requires multiple trial and error attempts to complete.
Also, spacing of the font in the intro is a little bit weird but that maybe just my eyes failing me.
And "u lost lol" looks very unprofessional, which can confirm the player's negative thoughts about the game in just few seconds. Contrast between this and pretty dark theme feels bad, and makes me feel like the game is uninspired, and the theme is more "lol, random" than "mature dark". Details matter a lot.
While I had issue with high speed as I pointed out before, I think that the true problems are not the speed itself, but as someone already said the variables (like for example damage dealt by enemies) because the controls feel really nice, and the high speed of the game is also nice, it's just that while it's fun to go so fast it's also unfair in current situation.
Anyways, good luck for both this game and any future projects.
