I do like the attention to detail of making sure the character can be seen behind a wall. Overall I think balancing a turn based combat can be a bit difficult in regards to keeping it varied. Things like typing of strengths or weakness in bosses and players can add that spice, if its something you seek on working on.
The visuals are quite nice, and similar to Octopath traveler, though I think the consistency between styles could be improved. In regards to making sure they are pixelated similarly, combining 3d models with 2D textures is also a good way to keep that consistency while keeping the advantage of the 3d visuals.
Overall I think its a game that if you tweak a bit more in the gameplay aspect and make the style more cohesive it could end up pretty good. If you decide to do some post jam updates.
