I mean, at least it's playable. You really should put more work into your games before uploading them.

Please polish, decrease the air time during the jump

Looks like an Okay game for someone new to gamedev.
the background is laggy/poorly animated .
the music doesnt really fit the game .
the jump mechanic could be improved (Disable jumping while in the air, the longer you press, the higher you jump).

It's nice, but also hard.
