Idle Clicker

The prestige upgrades seem completely broken; the cost reduction didn't appear to do anything when I bought it, the +10% CPS lowered the CPS multiplier on the prestige tab from x151 to x51 and the click upgrade, while increasing click multiplier to 1.10, also inexplicably lowered the CPS multiplier by 10.

The upgrades also seem way overcosted even when exploiting Resource Compression to reduce all generator costs to 1, though maybe they wouldn't be if they increased your multiplier as intended. Even so, you'll have all achievements long before you're able to buy the bottom prestige upgrades (which go up to over 100 points in cost per upgrade when 50 points total is the final achievement), so they don't seem to fit the intended gameplay progression at all.

Doesn't scale the game when fullscreen (game is tiny, only expands the background)
Prestige system is pretty poor, there's no benefit to staying around once you can press it, effectively no content past 10K coins
Resource compression upgrade reapplies every single time you buy a generator. This means the game very very quickly becomes broken as all three generators effectively become free.
There's just not really much of a game here, needs to go back in the workshop for a while longer

I would love to max prestige if you have more than the normal requirement
