My current streamed PB of Monolith: Relics of the Past for the category Null, F5 (defeat Overlord) on Normal Difficulty, Mild Lethality, Random seed, Loop 0.
I got a really nice weapon early and maintained it throughout the entire run: a Drill with the Backshot and Pulsewaves keywords. On floor 4, I find two keyword runes that allowed me to add Homing and Triple. Unfortunately, didn't get any mapping powerups to find the minibosses and boss rooms faster.
Monolith is a Rogue-lite, Bullet Heck SHMUP similar to Binding of Isaac meets Touhou/Ikaruga but with an arcadey, sci-fi/-fantasy theme. Floors are procedurally generated with a random variety of rooms filled with mixtures of ghost, mage, robotic, construct, and creature enemies, as well as 1-3 random minibosses (increasing as we descend into the facility) guarding keys to unlock the random bosses blocking us from descending to the next floor.
