The key to this game is memorization, as there are no checkpoints at all, meaning that if you die, you have to completely restart. The most tricky thing to memorize is the ground spikes. They will be completely invisible, until you are right on top of them, at which point they will pop up and kill you. Also, throughout the game, there are multiple "enemies" (the "do u no de wae" Knuckles), but they are easily avoided: simply jump over them, letting Banderita's foot phase through Knuckles' head, and they will die. You know they are dead when you hear a splat sound.
