zakiwana guide - difficulty select
the difficulty select room is a mini-avoidance, referencing wannyaaaaaaaaaa's final boss. you have to avoid the Imopo warps while waiting for an Imo warp to appear
Imopo is the impossible warp, whereas Imo is the medium one
if this is your first playthrough and ended up hitting one of the Imopo warps, you can press the R key to return to this room
in case you already have a savefile
hitting an Imopo warp will not overwrite your savefile. the only way you can overwrite your savefile is by shooting a savepoint, which is not possible on that difficulty. in fact the second screen in the game is a forced reset, which makes it impossible to progress without any savepoints
