The pogo stick mechanic is pretty awesome. One criticism I might have is that there are a lot of More Games buttons that can be clicked accidentally during gameplay.
I never thought much of the EBF series but I just started playing this and 3 hours later I accidentally hit refresh on Chrome. 5 stars. You may want to implement some sort of text file save like Legend of the Void.
It'd be nice if when you reset upgrades it didn't dump you back to the level selection screen. And then when you rejoin a level you have to go through the dialog again. But otherwise pretty awesome.
Not too bad - a little easy except if you hit the company upgrades a little too early. Hint - the last one will take your expenses from ~300k to over 1.5 million!
The quickest way to do that is to click the "Levels" button then go back to the hole you were just at.
