Some balancing issues: I have 18 coordination upgrades waiting, but it takes me usually 3 levels to be able to upgrade, which means I can never really use them. Maybe make housing cheaper (or the larger housing units much larger). It is frustrating to not be able to utilize upgrades... and I am at 443K housing on level 38 :(
I found a bug I think. When I restarted my browser, I lost a few items (dragon powder, mystery heart) when the game re-opened. There was also no update to cause issues.
Finished the game, level 51, everything gold with all achievements (so I got all the special challenges), but can't seem to get the stupid 5 pt. badge...
The bear defender ability triggers when you are hit, so you lose health to getting hit, a portion is blocked by the bear, then you gain life for the pet ability. The net gain can be negative or near zero depending on how hard you were hit/gear/points invested.
