Find what the unused entities were supposed to do
Several unknown entities are unused throughout the code.
These are mostly visible in the entities handlers table: all the entities labeled EntityXXXHandler are not used in the final game–but point to actual code.
For instance these two ones (but there are others)
https://github.com/zladx/LADX-Disassembly/blob/7f2c25ba394b75748e7ceb55677bc9d6b5115c70/src/code/entities/_handlers_table.asm#L120-L121
It could be interesting to understand what where these entities, and why they were eventually left out of the final game.

Maybe some leftover elements mentioned on The Cutting Room Floor could provide some hints.
NB : some of these entities are not used in the static room definitions – but are actually spawned at runtime (see SpawnNewEntity). So they are actually used (even though they are harder to figure out than the statically-defined ones).
