Prehistoric - really good, lost a few seconds in the boss fights because i got a bad RNG on my powerups The 1930's - almost perfect, got a few deaths but powerups RNG was really lucky Ancient Egypt - got lucky with the flamethrowers, boss fight was done almost perfectly because my minigun powerup ran out of ammo Feudal Japan - the boss was really difficult and i was close to get a game over The Future - Perfect, just Perfect i dont think i'll do more full game runs for now, im very satisfied with this run, i'll try doing some individual levels
