Beat it after a few tries, and really liked the aesthetic and music! Very reminiscent of the old 2D Zelda dungeons. I think it might be nice to have some more attack range or a little higher movement speed, but maybe that's just my own preferences leaking in. The purple enemies were a little challenging to deal with without using energy, and I feel like they were disproportionately challenging compared to all the other enemies that were generally not too much trouble to deal with. But between having such limited range and moving slowly, it was really difficult to close the distance and not take damage against the purple slimes
I did also get softlocked on my first attempt - in one of the rooms, a purple slime just left through the locked gate. Since I couldn't reach it to kill it, I couldn't leave the room and had to restart.
I only saw two items, the knives and the boomerang, and the knives seemed a lot more effective. The stun for the boomerang isn't bad, but it's hard to compete with the straight up damage of the knives. I also was unclear on how the upgrade that let you throw multiple knives worked? I took that a couple times in one playthrough but didn't really notice any difference in how I could use it.
