This is a really fun game once you get the hang of it.
I kept accidentally upgrading and picking things up. Maybe a dedicated button for these things would help. I still enjoyed the game, though. Great work!
Thanks for playing and fair feedback. I originally had it that you had to click a button to pick up/drop or purchase upgrades. Removed it to try and speed things up. Could have laid out the room better so accidental hits were reduced.
