I had to make a firework for a kid and even though i totally messed it up (crackle) he still loved it <3
I found it quite fitting in difficulty maybe slightly too hard for the relaxing vibe the game otherwise has.
I think my biggest critique is the lack of what i would consider multifunctional level design, as every element in the level only served a single function. And the visual polish of the fireworks for a game about fireworks could use a bit of love ^^
