Deltarune Hypothesis

Bugs and glitches
Let's say there was a MAJOR issue that needed to be fixed ASAP, and this issue wasn't found until many hypotheticals were released. It would require each hypothetical to be recompiled, AND for you to redownload the hypothetical just to fix the issue.

Engine changes
Since development would most likely consist of simultaneous internal engine changes, improvements and or additions ONTOP of developing hypotheticals, older hypotheticals may suffer as they wouldn't have these changes unless manually updated (By changes to the engine, I mean like optimizations, development tools, or just fixes in general)
