ONLY PLAYED THE DEMO:

Good incremental gameplay (I especially like that there are multiple upgrades that matter. Earning a box faster, opening a box faster, or how valuable the box is, that kind of thing.) Seems especially polished, I didn't encounter anything that immediately felt off or unintuitive. Only reason I'm not giving 5 stars is because the pacing seemed a little slow to my tastes, but to be fair, that could just be a demo problem. I can see the difficulty in including enough content but also not revealing too much of the game, and slow pacing is one way to combat that. Ascending the boxes also seemed weirdly ineffective, but again, I believe that is after the demo's stated goals, so I'm lenient on that.
