Scratch Nyanko Remake Projects: 21 Top Picks

You pick a Kyushu prefecture with the number keys, and the further you push from Nagasaki toward Miyazaki the nastier the enemies get. Every time the enemy castle drops past 999, 500, 450 and 150 HP, a tougher hippo-type boss spawns in turn, so chipping away at the castle actually makes the fight worse for you, just like the real thing. Your wallet upgrades through ten levels for up to 8x income, the cat cannon fires with a tap or the space bar once it finishes charging, and clearing a stage hands you 1000 XP that goes head to head with a cloud-variable world record.
