The platforming feels pretty solid for most part. This type of game may work better in sections, which can have shorter timers but less falling distance to set you back. The visuals could use some extra cues and variety, like maybe a crouching sprite and a bit of a shake when the lust bar fills.
Congratulations on making your first game! It's great to see that you didn't pick something too complicated, a small but fully functional project is a better way to start as a developer than by making something too ambitious and broken.
