I'm going to contradict previous feedback and say that I actually really enjoyed the 3D world. I think if you gave the trees and buildings a bit of a cel-shaded look, it would blend nicely with the cartoony style of the billboard characters. The world felt very mid-2000's MMO to me, and I loved that. The encounter system, while appearing basic, also was fairly fleshed out. Spawning the battle in the 3D location where it actually happens is really cool.
I do agree however, with most of the other feedback given. The game actually has a good bit of potential. The turnbased JRPG combat is all there, just needs a bit more refining. Player felt glacially slow, especially going up and over that bridge, dear (necro)lord.
Overall the game felt pretty easy, I might have lost 1 basic skelly the entire playthrough. Due to gamer knowledge I kinda guessed what the status icons did (poison, stun, etc.), but I think some text describing what is going on might be beneficial in this scenario (damage output, health healed, status, etc.).
The idea of earning the units you defeat in battle is cool, but kinda felt like you needed one more mechanic to have the units be a resource instead of a collectible. So maybe if they died again, you would lose them permanently. In future versions you could even name units, almost like Darkest Dungeon.
Overall good job! But I swear if I "wolf sound effect. wav" one more god dang time...Cheers!
