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.
