Congrats on completing your first itch game and game jam! I like the smooth animation; the game still conforms to a turn-based grid but feels more fluid and natural. The graphics are similarly appealing, with that nice parallax thing going on that adds imposing shadows onto the corners, allowing enemies able to pounce instantly from the corners. All the essentials are implemented well here: there's an inventory and item upgrade churn, a nice little output terminal and a multi-level design that gets challenging very quickly. I appreciated the compass to guide the player too: there's a lot of dead ends in the maze!
For constructive feedback, the item system is good, but it was tricky to tell what upgrades were materially useful or better than what I had; this makes it difficult to adapt to the onslaught of enemies and feel there's a sense of progression. I think a few little tweaks, like visible item stats, could go a long way to helping the player feel they're in control! There's lots of items hinted by the design, like yet to be implemented scrolls, that could help a lot as well!
