Thanks hippodarren. I realized shortly afterward that all I had to do to check was watch the refund price right before and after I bought an upgrade :P
There's one problem with this game. On reverse mode, I stopped playing after I had cleared 51 levels so I could get to the last mode, and I made it to level 130 by literally doing nothing.
I only even had to use the thump to flip things that were stuck up against a wall. All the other times I just stood next to the shell, pressed toward it, and jumped. This game needs either enemies or puzzles so that it has some sort of gameplay.
Instantly going back to the first level after one death is stupid and makes the game way too difficult to get anywhere, especially considering the already iffy controls and viewpoint.
not bad ,but it feels like the ball needs some momentum so that when you're going one way, you don't instantly turn the other way by pressing the opposite arrow
There seems to be a glitch in which I sometimes get stcuk when rolling uphill and the platfrom I'm on is near the top of the screen. This has resulted in my death twice now.
