Most notably in the Algorithm & Heliophage.
In the Algorithm, If Isaac shoots you into the sky when you land the killing blow, the bonus score vanishes before you hit the gorund. Also, dependng on which banter segment plays at the end theres can be little to no time to collect what remains.
In the Heliophage, when you drop Rendain theres a bright flash that blinds you than it ports you to his cage for the final scene. If your not on top of him and collecting drops blind, you end up getting nothing from the FINAL BOSS. I’m sorry, but letting people get gypt on the end boss loot is like kicking your players in the sack than laughing in their face. There’s no reason to do it unless your goal is to troll your players for kicks n’ giggles.
Those aren’t the only levels with end boss issues, but they are the most notable (as they bookend the entire PvE campaign). Please make some changes to those poor design decisions and hire better QA testers.
Thanks for your time.
