Really cool! I love the different scratch card mechanics.
I'm not sure how those interact with the autoscratcher, since I liked to peak at the contents before deciding to fully scratch or not. Maybe that's a good trade off for automation though! I think making the money automatically collect or cards automatically feed into the scratcher would be great extra upgrades.
I'd also love to see some upgrades for the player's skills (size/power of scratching) but maybe that'd need control too so you can still peak if you want to.
