It's easy to see how much effort went into this game. It's cinematic and well optimised. There were no bugs that I found, but I did feel like there wasn't really much gameplay to be bugging out on. I am not a fan of turned based battles, so this game sadly isn't for me. The only thing I would comment on is that I found it strange only the heroes had face portraits. If you wanted to add those in but couldn't find resources for emosets, you can find some really nice ones here. (Or if you think the default faces look too out of place with the generator ones, you can find some generator style ones here.)
Good luck with your game, and happy making! <3
