First of all, fun game, especially once you get past the first few upgrades. Two things: I've maxed everything out, but the game doesn't want to enter Phase Rainbow to give me the final achievement. It's been running for maybe 40 minutes and I have 21B coins and 17B gems, and nothing has changed. Second, this is cosmetic, but the music cuts in and out in the later stages when there's so much going on. Maybe a priority thing?...

Some of them are given in like five minutes, others I've gone the better part of an hour. There doesn't seem to be any rhyme or reason to it.

as topic.

The Split ball and Area ball elasticity upgrades have flipped descriptions. Clicking on the upgrade tab and leaving the tab after beating the game will re display the congratulations message.

By the time you hit about 90min in you are basically at the mercy of waiting for more bricks to appear. There should be a shop upgrade to speed it up, or allow it to be controlled.
