Aghh!
I became invincible at around level 25 or so, and just nuked things half-asleep til level 100. But what the hell, why can't you win? If I'm going to play til level 100, I want SOME kind of sign of victory. Hitting X and mass clicking the tanks that survive the infinite explosions of mass untimely demise for 75+ levels is hard enough on my patience, but then I don't get to win!? It hurts to see "Level 101" you know. What is this, anyways? I don't mind not winning so much as not reaching an end, and doing the same thing with NO change for 75 levels. Honestly, it's probably my fault for not knowing when to quit, but AAAAHHHHH! There goes some incalculable fraction of my life, wasted with all the other fractions and large chunks of my life that seem to disappear like the mass armies that are destroyed by one of my thousand nukes I have in stock, increasing my score to now 3 million. Again, AAAAHHHHH!
