Just had my first go of the newer version and it seems good, tho as i didnt beat my old score i dont know if i'll get the same bug as moon got if/when i do.
Few changes i noticed, mainly the NAN bug seems fixed
so no more loosing all your gold by clicking on the wrong thing at the wrong time.
Laser turrents are now cheaper to buy and 1st few upgrades are cheaper too (tho you do need 25gold before it lets you buy 1 still, even tho it only deducts the new price of 15gold from your bank)
Mobs now notice when you sell something, so they no longer walk round an empty space where a turrent used to be untill you build a new one.
The X button no longer works, so if you pick a turrent from the menu and decide not to place it, you have to place it on top of an existing turrent to cancel it.
