Not a bad game. There seems to be some issues with the cost calculations though. Going from 200 to 300 of the Blog costs 630 Quintillion, yet the Car Lot, also going from 200 to 300, only costs 485 Quintillion. And going from 300 to 400 for both the Power Company and Tech Company are cheaper than the Hotel, more than half as cheap for the Power Company. There's also a minor clipping issue between the Bank Building and the Power Company building, at least when the Power company is 300 and the Bank 200, the Bank sticks into and out of the Power building a bit. There is a bit of strangeness with the timers, especially the higher value ones which imply an hour long wait but are actually much shorter.
Other than that, quite a good game.
Hmm.... from what I've played so far (3 dragons down) Crit is an overpowered stat. It's scaling makes snowballing very easy with attack, because once you get it past the 50% mark, you effectively have double the attack damage for every hit. I've got mine up to about 65% and I can clear everything with minimal speed and relatively low defense. You might want to lower the scaling to 1% per upgrade instead of two, and lower the max allowable crit rating.
Of course, this IS a game where the whole objective is be completely overpowered and a thing like balance shouldn't really matter... but dammit, the D&D rules lawyer in me demands balanced mechanics!
Man so many nostalgic D&D monsters. Ah I can just watch this for hours. One thing though, you gotta make it so that multiple quest items don't count against your encumbrance level. Its a pain in the butt when I have 16 of 17 nails and have to go all the way back to town because I can't fit the last item.
Most seem to buy attack and defence, so if you find how useful critical is thats good on you :) Maybe I make it a bit more calm in sequel :P
