This game is super stylish! All of the assets are well made, including the lovely dragonbones battlers (though I'd expect no less from you ^^) The only thing I would have liked to see was perhaps custom balloons too.
It was a bit weird to have a flee skill and the standard escape option. You could try using SumRndmDde's Battle GUI Core to hide the party command though I'm not sure how compatible it'll be (and the flee skill does miss the cool escape animation.)
Onto the gameplay, unfortunately it wasn't for me. I'm not particularly fond of turn based battles, and this had a ton in. Although you can escape, it puts you back to save points and all the enemies respawn so it wasn't really avoidable. I did get up to the (what I assume) was the final boss, after around 50 mins. I tried twice but couldn't win. I was curious about the ending (and all of the golden skulls), but since you have to trudge through battles again to get to the boss, I didn't feel up to a third run.
So I'm a bit disappointed on that. I enjoyed the atmosphere though, I just think it wouldn't hurt to cut back on the number of skulls. Since there's no stats and so no need to grind, it would help to be able to enjoy the exploration a little more without constantly getting caught, though I am bias XD Great job anyway!
