Very fun little game here. My best run so far:
Cycles Survived - 28
Enemies Slain - 888
Highest Nub Count - 173
Tokens Left - 8234
Final Score - 22416
My downfall? Too many mines, couldn't train new nubs quickly enough because I couldn't build enough buildings after stockpiling way too much of the currency. I did in fact get to the point that I ran out of space about ten cycles before the raids became too difficult so being able to sell buildings would've probably gotten me through a few more cycles, but managing the space without selling was also fun. Also didn't have enough melee nubs to keep the enemy robots off of my massive hordes of third eyes & archers so the enemy robots were nuking my ranged forces. Maybe the tiny nubs would've provided more value than I expected.
Overall had a lot of fun, definitely kept me well entertained for a little over an hour. Great job making this.
