I really like the concept overall. It is an interesting approach to roll a dice to see which attack the character will use. Nonetheless there is room for improvement. 1. When I have two characters against 1 opponent, I believe both of my characters should attack in the same round as one attack from the opponent. Right now the opponent gets two attacks for each round when there is only one opponent. 2. It is a bummer to me that all of the artifacts impose negative stats. I found myself not really wanting to equip any of them because of that. 3. I always check to see if levels are can be replayed in games like this but it is lacking here. Like I said, you have a good start and I like the concept but I think there is a lot more you could do to improve from here.
The tooltip that pops up over the upgrade button blocks the visibility of the level above. I was really enjoying the game but that popup is really getting annoying quickly.
I really liked the idea and the play of this game for the first thirty minutes or so. All of the sudden it was taking thirty minutes to heal my party and another five minutes to upgrade before I could do the next battle. If the healing time was cut down substantially, I would probably keep playing. As is, I can't give it more than a 3 stars because of the time between fights.
I changed the tooltip positions with the latest update. I hope that gives the advantages of the tooltips without hiding important information.
