BioGun - All Bosses (No Damage) & Ending
70A compilation of the bosses available in early access for BioGun defeated without taking damage (except for unavoidable damage) and the ending. As a new pig vaccine designed to stop the virus that has dogs on the brink of extinction you get to rough up a bunch of viruses in your creator's dog.
The transition for Diromitis' second phase has an unavoidable attack that brings you to 1 hp. I considered switching to the Critical Blaster chip to enter at 1 hp but that would have meant doing the chase all over (and there's a few bugs there). Likewise, the event occurring after defeating all three dooper spawns pretty much has unavoidable damage (you can leave the room so I guess you can cheese it by just not being there) but there's no boss bar so it's not really a boss fight.
Otherwise, despite releasing in early access and having some bosses not fully implemented and a lot of side content unfinished this is so far a well-done Metroidvania. The developer is very responsive to bug reports. Even if you prefer to wait for the full release I'd recommend checking it out at some point as this is a solid entry in the genre.
