Even if exp is logarithmic, it makes a lot more sense to display the money required to reach the next level... How much good does it do for me to see 500 exp left, whenever that could take hours (even though the 9000 before it took 30 min). I just end up calculating the money left anyway. You have the info why not display it...
What is storage for??? I stocked up before a new estate and it didn't keep it. As it is, there seems to be no point in storage since we get auto sellers.
I think there is a bug with the Slow-Mo Power and Limbo multiplier relic. I have +5 Limbo relic. Currently, the Slow-Mo power text shows 7.35 but the actual power increase is only 2.35. I haven't purchased any Limbo yet. Not sure if I should be getting 7.35 or if the text should read 2.35.
It would be nice to have another collapsed view that shows the speed, friction and power of a particle without the upgrades. This would make it easier to see all pertinent information. (Especially after all upgrades have been purchased)
Now this is what embodies why I originally fell in love with kongregate. Short but fun with focus on polish over graphics (not that they are bad). Great work! 5/5
This and some other visual bugs already fixed but will be up on the next update.
