Pretty bad game. The "bonking" is always exactly the same, with no evolution or paradigm shifts (no, the simple upgrades don't truly change how the game feels to play). The "merchants" which auto-farm gold don't enhance the game and don't make much sense seeing as you have to be in the merchants screen to farm their gold, and seem to only be a replacement for the actual gameplay.
Typically, the purpose of a game like this having the short "rounds" with upgrades in between is to let the player feel like they're progressing further and further as they purchase upgrades. In this game, the first round and the 100th rounds are basically all the same, except that the final upgrade "Perfection" will shower the player with gold... after gold has become completely useless.
Impressive for something made so fast, but there's no reason to play this.
