Cool game, just one suggestion, after you level up a few times the cash reward for winning should go up. ie after you reach level 5 you get 50 coins instead of 30 for winning.
Thanks, I added some cheesy music and a jump sound ;) I might put in some more stuff - thinking of falling/disappearing platforms/other surprises. But this game was done for a 3 hour game jam, thats why it's a little - limited - ;)
Thanks! You get more coins in Medium and Hard rooms!
