After carefully reading all the subs arguments on ontological fundamentals I have come to the pictured conclusion
I played this game in early 2000s on PC so it came out before then. It seemed retro-ish at the time.
Top-down view where you controlled a knight delving a dungeon and all your enemies were 1-hit slimes. Knight held their sword straight out in front and you either turn the knight on the spot or move a square in any direction.
It was turn based in that the slimes would only move when the knight either moved or rotated. Object was to position the knight so his sword would hit all the slimes. Slime number, starting position and environmental obstacles increased as you got deeper in the dungeon so you had to think through your moves carefully.
No upgrades, items, extra moves or anything that I recall. Just progressively harder puzzles with the same mechanic.
I played it on PC and am pretty confident it wasn’t emulated but could have been a PC release of an earlier console game.
No idea of the name. Searches for knight slime and dungeon don’t bring up anything.
