The music and minimalist vibe is charming. I'm guessing the inverted controls are intentional to give just a bit more of a gameplay challenge. Though I liked it and it's good for 1 hr of dev time, compared to other games that's I've played till now, it's a 5/10, which might quite high for such a game, but I'm not being charitable here. I do like it, played till lvl 45!
