I'm pretty sure this is a troll, but just incase it isn't...
Uhhh, what? The game is just painful to look at. The style of the background does not fit the style of the objects and the character is just a non-cropped square image of some puffins.
I couldn't see the ground elements like the spikes at first as they just blend in with the ground. There were no instructions in the game or description, which you might think is nothing as it's just the basic arrow keys. This however matters for people that don't play platformers as often, and are unfamiliar with platformers.
Points for having something to make me click on this, as the thumbnail was nice. It ended up being clickbait though.
