Well I've tested out the TI-83 version of line rider for a couple days and... it sucks. It's not even close to how the original Line Rider plays. The physics are messed up. For example, if your in a loop and there is a gap in the top of the loop sort of like an upside down jump, you will fly straight up in the air instead of continuing in the direction you were going. It's really not fun compared to the computer flash version of line rider.
