1700 was my best after two attempts !
Nice but I'm not sure the game uses this effect to its best. I feel like the sprites are too distorted to be clear and attractive to the eye sometimes. It still gives a very nice "psychedelic" feeling. Maybe not using water on the bottom might help having less messy sprites, because it's the part that tends to get the weirdest appearance with this effect.
Somehow I feel like this concept could go further with other gameplay mechanics than run and jump. What if the player controlled directly the path ?
Otherwise, to stay in the same kind of gameplay, I think it'd be better to have a larger path and a gameplay more axed toward avoiding than jumping. I find it more satisfying here to avoid the small rock by strafing left and right than jumping.
It's not a negative critic tho, I enjoyed it and find impressive that this can work on actual hardware.
