W/UP arrow: Jump Space: Dash Avoid the spikes for as long as possible. Dark red spikes are too hard to jump over so you can dash while in the air to get over them.
I don't know why I chose red. This is a runner game that I thought would be fun to make. Some of the mechanics are really difficult, that's why it's not progressive. I tried though... I know the thumbnail looks like OASH, ORSH, or DRSH. It's because of the art style. It's one of my personal favorites though.
