Ah, I see. Actually your comment about the enemies and what they do made me realize something -- what if there are tooltips for the mobs?
Something I struggled with in this version is the crystal/obelisk thing. I didn't know what it does, I kinda guessed it gives buffs (armor?) to the units around it. But I wasn't 100% sure if it was the crystal or the ghoul. Would be great if I can mouse over it and see a description about the unit (maybe even possibly their attacks as well -- though I am not so sure if that is a good idea and spoils half the fun).
This also brings something interesting, what if I can click on the items on the ground before I have to go there to find what they are? It'll make the decision process easier. Specially when you aim to make levels challenging, if replayability is a thing (which I didn't feel it was since if I lose I don't get anything out of the loss) then you could leave it as is since at least if I waste some moves and make a mistake going for a certain item that turns out to be not so helpful I'd get something out of the loss.
