We played your game and we defeated the last boss!! It was quite fun and engaging to open all the doors and find new swords. Some enemies were a bit tough and having a skill to do a little bit more damage would have made the fighting of the minions feel less repetitive, but it was still well made and it was nice to see details in the scenes like the Skellys making potions or having a club of their own haha The little blue skull companion was a nice touch too, it could have been an interesting full character on its own :) (The bear skull hero was already amazing though, loved the concept!)
We actually didn't encounter any bugs so if it can reassure you, it felt like a smooth playthrough from the beginning to the end!
Overall, really good job, keep going foward! :D
