Cooler fans are blasting at full speed only to display one number going up somewhat fast

The main "selling point" - descriptions of the upgrades - can't be viewed for most of them because you have to scroll away from the text display

Specials disappear when bought - so you can't read their descriptions again

The game tries so hard to be "cool" and "educational", but at its core it's very basic and uninspiring (no problem with being simple, but don't be an overheating showoff with that)
