that's a very ambitious game for a jam! Equipment upgrades, stealth, combat, procedurally generated dungeons, dynamic field of view, etc.
The dynamic field of view was really cool and I got a good sense of progression when I managed to purchase upgrades. Dodging felt good when I managed to get the hang of it.
The main issue seemed to be the balance of the dungeons. The game was at its best when I encountered a dungeon with a reasonable amount of enemies, then I could strategize, choose my approach, adapt, and so forth. But sometimes I got a series small rooms clogged with guards and it was very frustrating.
With a few tweaks (ie balance and a more varied level design that really enables a stealth approach) I think you can really emphasive the good parts and diminish the frustrating ones.
