Thank you the comment!
Completely agree. Both me and the artist are at fault here.
On one hand, I spent waaay too much time refining mechanics instead of level designing and playtesting to find these UX problems.
On the other hand, it was my partner's first time making art for games, so he created all of the player sprites with the flames.
I was supposed to separate flame from character but didn't have the time. About 80% of the game was made in the last two days...
