Great game! Two observations: Entrances to quest dungeons aren't visible enough. You can enter your inventory before getting hit to avoid damage from tough monsters :P
The game got very passive, there is nothing to do during raids after maxing out shard gains. Imo, when fighting a dungeon raid boss it should be possible to prestige. There's no point in active gameplay otherwise.
The experience gained to time spent on combat needs reworking imo. I can beat Sepitus on insane easily but its still better to just keep on farming Skeleton King for fastest exp gains ;/
Shield recharge doesn't seem to work. Could you implement something like a "buy back" option to get all the gold back to try different upgrade builds on specific levels?
Shields recharge working fine, its simple very slow and recharge is active only during gameplay (not at very end of a level, means that if you have only last enemy to defeat and wait to kill him, the shield recharge stop after a couple of seconds). But i think to speed up the recharge rate in the next game update. Bye!!!
