This nyan cat have a passive ability I just can't counter. He's just big and there is no upgrade that can make me beat him faster. I do the remaining of the level faster and faster due to upgrade, but then I'm stuck with that nyan cat. For a longer and longer part of the game. Congrat, you found a way to make an upgrade game where you upgrade your capacity to not being able to upgrade any more. Honestly, without upgrades this upgrade game is just crap. I'll vote for the part I did the most : The nyan cat with no relevant way to upgrade.
