Hey,
The game is super minimal and looks great but the difficulty is way too high for the given controls which are making the game fail without even collecting a single point. Also, as there are no mentioned controls anywhere, it's quite difficult to understand it first. However, this game also requires polishing and improvement in these terms-
- You can consider adding a pattern background that's scrolling as you go to look good.
- You can change the color of the entire game slowly by shifting the hue.
- Polishing the controls would be the primary task here, as it's currently not that appealing.
