this is not bad for a new developer I suggest increasing the players control over the character. faster flip speed, and higher jumps.

This is a single level platformer. I'm a newer developer, so hopefully it's a decent experience.
Controls,
You can increase the speed by pressing UP ARROW KEY
Flip with RIGHT and LEFT ARROW KEYS
Jump with SPACE
Painfully slow response trying to flip, and it would be nice if up key added more speed downhill.
Because gravity.
