Ok, here's are the points:
- Increase the player's jump distance because it's ridiculous how small the distance is the player covers while jumping.
- The parallax background is nice but make sure to improve the artstyle.
- sometimes the procedural generation generates comically spacious areas where jumping through them is totally ridiculous.
if you worked with lesser time and submitted late, I understand. but next time make sure to make a better game with the advice I gave you.
