Thank you for playing my game! Wow, that's a long review.
This is not the first time I being told that my art clashes with the RTP. I actually planned to draw my own tileset for this jam but when I start drawing it, it doesn't feel worth the hassle. I also have drawn a few battle backs for this game, but I didn't use them because they looks ugly. I guess I still need a lot of practice drawing backgrounds.
I'm glad you like the Dispel Strike mechanics. I also try a couple of skills that can synergize with each other. For example, David's third skill, Revenge Blade which deals more damage at low HP, synergize well with Necessary Sacrifice, David's sixth skill that make him immune to all incoming damage while decreasing his HP until 1. This skill can be enhance further by Davina's third skill, Void Thrust, that double physical damage taken by the target for a few turn. When the immune effect of Necessary Sacrifice is gone, David can use his fifth skill, Draining Strike, to bring him back to 50% HP. In case of the three mages battle, their barrier would decrease 99% of incoming damage but only one time. Therefore you can remove all the barrier just by using a weak AOE skill like Demon Lord Roar. I should have present all the mechanics better. Making the game intuitive always has been my weakness for ages.
For the boss rush reformatting, I kinda agree. I actually enjoy making boss battles a lot more than the filler encounters. Still, this game is already finished and I do not have any plan to change it (except for balancing, bug fixes, and typos). But I will consider a boss rush format when making a new game. Thanks for the suggestion!
