Yeah, I use a controller. I don't think it is a 'simple' game. On the contrary, quite complex and deep once you get into it. It starts as a simple-looking game, but as you progress, you get one ability after the other, like dash, double jump, wall jump, super/crystal dash and along with many unique boss fights and platforming challenges + amazing lore and music make it very complex.

The video talking about its Lore is more than an hour long lol.
