Were you rescuing people?
In any case, you can flip the fire bar to easy in the main menu, that could help! I know it's a hard game, so don't take it wrong, hahahah
I think I might be tuning the levels too tightly so someone who would know the game too well would have fun (i.e. me), but this isn't good for someone starting out
I will find a way to lower the difficulty a bit to have a "normal" difficulty later though this will probably come in later on, when all levels are done! (hard to do otherwise)
