Good looks, servicable sounds and UI, but (for me) it was barely playable. I'll be blunt:
It's *slow*. Takes too long for the character to traverse, takes too long for enemies to complete their turn. I'd like to make meaningful decisions, but there aren't any to make for the first few turns, and I end up staring idly at the screen. This would be hard to swallow for a full production, it's even worse during a game jam, where there's dozens of games to go through, and if a game doesn't give the player something to act on right away, it's going to suffer in ratings.
In my eyes it needs a few breadcrumbs in the beginning, snappier movement, and speeding up turns of invisible enemies.
I do applaud attempting to make a tactical (and functinally complete) turn-based game during a jam. There's a ton of systems to make in a short span of time. Kudos.
