Hi there! Here are my feedbacks:
- The main menu screen is a bit simplistic. You can label the help button as 'How to Play' or 'Help' instead of just a question mark.
- The music and sound is good but a volume control is useful especially for people who use earphones.
- The game control is unresponsive at times. Jump sometimes work and the player might jump too high. You can recheck the code for any bugs that lead to the unresponsiveness as well as the jump height.
- In-game HUD are much better with labels so the players can know what each indicator means.
- The timer is too long. It would be great if the players can extend the time using pickups on each level.
That's all. I hope you can continue making games. Better you have potential.
