Thanks for playing.
The overlapping sound effect from the jump and trampoline isn't intended, it needs a small check to make sure it's not touching the trampoline.
I mostly made the coins as an extra collectable that is optional for people who wish to get it.
Spike traps currently reset when the player goes back to the bottom of the screen. Might make a new timer for resetting it, I'm trying to figure out the best balance for it since the game is made to be a rage game and I do want it to be hard. There is control with jumps with controlling the gravity of the frog (pressing and holding S for degrees of control to cancel a jump or to make a jump shorter along with how long the movement keys are held for distance, so the movement keys can be held and using the S key can correct a jump if caught as a mistake half way through it.) Maybe it is too punishing, but I'm really trying to figure out a balance for everything to make it difficult to fit the rage game genre of things being very punishing.
