I didn't have to reset but I had the same problem as Cravinch, however the game itself reset my information. This is bad... auto save didn't work at all. I'm dumping this game from favorites. Good luck fixing it.
When I finish playing for the day, I save the game and exit my browser. The next day I open my saved game and EVERYTHING in the Bestiary is gone. Including the first 2 bosses I scanned.
Nightmare = 99.9999 you get the idea... % impossible. He tosses more and more swords at you, the laser hurts and like impossible to dodge... the rocks dont hurt you at first, but they do later on. You get very little warning besides a shadow... you get no weapons besides the "rocks" to hurt the nightmare. wt.f provide something, he's got a SWORD.
Can't even get through without some very difficult losses in the start. More then 1 tower at start is needed yet you do not provide enough money/starting tower costs to much.
Was boring and not very good. Needs to be made more... up to date with current graphics appreciation but that's just me. It was a good job if made from scratch, just not a good game I like. Sorry. 1/5
