A lot of mistakes throughout, I've had several runs going better than this heading into the final stage (Base), but managed to throw them all away at the exact same spot, even though it's not a difficult stage. Got a bit trolled by the only RNG in the game, the boss on Base, but I finally managed to complete a run. Sub 21 should be possible with a really solid run and not getting RNG trolled.

Played on bgb 1.5.7
