Enjoyed what I played of it! Got through three rounds so far, but at this point I've bought everything available to me, have so much time saved up on the clock (40+ minutes), and the upgrades I have solve so much of the puzzle on their own that I'm putting it down. Will be interested what a cleaned up version is like; I think you'll have to carefully consider how to still make it worth it to actively solve puzzles vs just letting the auto-triggering upgrades do it for you.
