I enjoyed the game very much. For whatever reason I have always been attracted to games like this and I always like it when these kind of games come out right. One thing i would like more of is an extensive upgrade system. Keep adding to it and keep making games.
I really like the game! One thing i would like to see bows that could be dropped on the battlefield. The bows could have elemental damage or maybe perks such as knockback. That would cool if you could work that in.
For any new players, don't try to fight every single monster in the dungeon. If you do this you will find yourself running through mana and health potions. Pick your battles
One suggestion, how about a buyback menu. I just sold an awesome crossbow and cant get it back. Just add a buyback menu for anything we have sold in the past 5 minutes.
Just a thought, but maybe after each rebirth that if you use the same race then you could have a boost (even just a slight one like +1 or 2 for each stat) or instead of boosting all stats you could let us choose a stat that we wanted to boost. Personally for me I would invest in Will and Dexterity. It would be awesome if you did add it but it's alright if you don't. By the way this is a great idle game.
