The game contains only 3 levels but I don't think that's the issue. Graphics, music, gameplay and level design are all amazing. The ads can be a bit irritating however this is an offline game so you can just turn them off. If you're familiar with Geometry Dash you should give it a try since you can grab a few cool icons to use in the full version of Geometry Dash, but if you're not familiar with GD I suggest playing "Geometry Dash: World" first before trying meltdown.

Didn't expect to be engrossed in an RPGMAKER game again these days, but this game just DELIVERS. The premise is somewhat hard to properly explain (without spoilers) to entice new players but I'd say it's definitely worth playing.
