A 2d platformer. In general, I do not like, and am not good at, 2d platformers. However, this game is a masterpiece. Playing each level gives me the same sense as mastering a piece of music. A lot of the game did not feel like the difficulty came from tricky platforming, but rather a sort of puzzle whose solution was being in the right places at the right time. This was a welcome surprise and is the main reason I almost 100% this game. I resolved to aquire every strawberry in a level and complete that level's B-side before moving on to the next. Playing this way absolutely broke up the plot pacing, but the added challenge sharply increased my skill at the game and the later levels were less frustrating than if I had not played the way I did. I would play one new level for several hours until I either completed it, or developed a bruise on my thumb from pressing the plus key switch, usually both. There are also a plethora of assist options so players of all skills and ability can play Celeste.
