It's an interesting short game/proof of concept, but falls short as a full experience. You are banking time to buy cogs which accelerate the passage of time, through an Antimatter Dimensions-like tree of autopurchasers of the next step down. I like that continuing to purchase the lower tiers gives you meaningful bonuses by continuing to multiply x1.1 per manual purchase even when autobuyers are generating far faster than you can click.
That said, this game is linear -- just speed time up through the tree until you accumulate enough time for "The Big Freeze". There's a prestige mechanic, where that trades in all your progress for Eon Seconds, but the prestige appears to be broken -- you keep all your autopurchasers on reset. Frankly, I'm glad for the bug, because accumulating eon seconds would be a glacial grind if you had to go through the 45-minute bootstrap process for every prestige. As it is, you can prestige in under an hour and finish the game in another ~10 minutes, and then once you complete the final achievement there's nothing else to do.
Others have outlined the UI complaints and I won't rehash them. It's very clearly a rough and early game and the developer doesn't seem to want to overhaul it, but it's enough to get me curious to see what they made after a little more experience.
