Thank you a lot for playing and for all the suggestions!
Yeah, cancelling actions can seem a bit awkward at times and it begs for undo button as well. It's funny, because those quality of life features that you mentioned were all on my list of things to "potentially implement", but I was so extremely tired on the last day of the jam, that I just decided to leave it as it is.
Also, items that have to be in hand-carry were originally implemented and were supposed to be in the second to last level (that's why in that particular level there are no new mechanics), but it was also scrapped due to time and exhaustion :D
