Shows promise. Right now there's not much to do. There's three upgrades, three spells (which also double in cost per cast so they are basically upgrades with expiration dates) and three post-prestige (pink) upgrades -- the game is pretty aggressively linear. It seems to be under active development, and the Combos introduced in the latest version provide a fresh mechanic, but it's a grind to get there -- they unlock close to the end of available content, about half an hour of a total 2-to-6 hour game.

There are also a few rough UI edges. There's no automation for the blue upgrades, so every prestige requires about 75 clicks to max your kit back out. The random roll for row bonuses provides needed interactivity, and it's a good gameplay element overall, but it requires a great deal of churn to reset and reroll the bonus because if you get stuck with low numbers you absolutely seize up shortly before progressing into pink. (Also, once you go to pink you can no longer adjust the row bonuses for blue without prestiging, and there's no mechanic to reroll pink bonuses without prestiging, so the push to 1 million pink cubes gets extremely luck based.) I agree with the suggestion downthread to offer additional upgrades to tweak the row bonus rolls.

That said, if this expands into having more gameplay elements, and the balance was refined to take out the luck reliance and the long stretches of no interactivity, this has a solid foundation to build from.
