Terraria, Hunt of the Old God - The Sticky Singularity, Goozma
this fight is the best boss fight i've ever done in my 2.4k hours of playing this game ever, and its difficulty while being absurd is also fair at the same time.
i had a lot of fun with this fight, and beat it a second time to upload it to YouTube. I don't really care what anyone says saying something like "Fabsol doesnt know how to make balanced boss fights!!!"
The fight is both amazing in its visuals, soundtrack, and actual fight.
