EDIT: I'll be posting more descriptions here when I find more cool games in need of ratings.
Abandoned
This is a criminally underrated full-on Metroidvania game that I found which only has 6 ratings. It has a lot of cool powerups and progression and an expansive world. It also has amazing sound design and is really polished.

Duck-like
Really well done rogue like topdown shooter with really engaging gameplay, I had a lot of fun with this one.

8 - Beat Dungeon
There are many "dungeon crawler rhythm games" submitted to this game jam, but of the ones I've played this is the most polished and fun. Instead of just being a normal rhythm game with the prompts reskinned to attacks, you actually get to choose your moves but have to do it to the beat.

Skull-a-mania
This is a solid bullet hell game with great art direction and sound design. It is a little short but I really enjoyed it.

Monster Casino
RPG with a pleasing visual style, good dialogue and a unique poker-based combat system with abilities

I've been keeping a public collection of my favorites from this jam, but the rest all have a good amount of ratings. I will drop the link to my collection though in case I uncover any other hidden gems to add to it.
