It was very exciting to see some MoTM action in MZ! That artwork and action sequencing was really good. It was also cool using that radar mechanic for treasure. Voice acting was great as usual, and I thought the desert map was really nice. Cool UI info interspersed throughout. Below are some feedback points I hope can help!
For jam games I typically don't like random encounters. After 2-4 battles, I found myself running from all of them, which is not fun gameplay. It also creates a conflict between exploring for treasure and battling. If there were a few enemies crowded around treasure points, that creates some cool tension, and makes it less of a chore to walk around looking for stuff. I would have preferred a few scripted battles at map points, along with a nice amount of hidden treasures to find.
Action sequencing could use just a tiny bit of improvement, particularly in the impact of hits. Shield bash, for example, needs to feel like a solid hit. A little animation on the enemy, some knockback, small screen shake, all would make the hit more satisfying.
I also was confused for a bit about the "weak" and "strong" popups. I feel like they were reversed in this game compared to other games, so I thought my attack was only doing 4 damage even though the enemy was "weak" to it.
Overall a beautiful entry. Had lots of fun despite the short journey.
