Thanks for playing and the very detailed feedback - clunky is definitely the word for this game, I wanted to improve the tutorial but didn't get time so the reference sheet was a "bandaid" fix for it just so the information was somewhere in game. Genuinely forgot to give a tutorial for dragging, probably would have been a good idea. Undo was a late addition, caused by level 5 being a bit vicious for lack of a better term, so the slow pacing is to avoid bugs that occured when it was spammable that I didn't have the chance to otherwise fix.
Very tempted to come back to this after the rating period to fix it up and polish it.
