It's a very cool aestetic. I would have liked some more information on the stats and actions. What does DEF and MAG do? Is DEF an active ability that just affects the rest of the current battle, or is it also a passive skill that makes you take less damage?
I ran into a couple of bugs. If you end a fight right next to an enemy, you can push that enemy, it doesn't trigger the battle scene until you move away from them.
If you have two enemies right next to each other and approach the closest one at high speed, you first see the name of the first enemy, but it changes into the next one. Probably because the player keeps drifting to the next one.
I really like the super low res graphics, but the buttons and progress bars break that limitation being rounded rectangles. I think I would prefer if they were also low res.
Very well done, I enjoyed it!
