Flash might be dead in practice but it is alive in spirit in what seems to be a tribute to a few dozen free online games you probably already played 10 years ago, down to the pitiful length of the (mostly extremely easy) base levels and especially the questionable rng fiesta of its hard mode, because whomever made this absolutely bought into the idea that a hard game is one that kills you with next to no counterplay until you just luck through by repeatedly throwing yourself at something you have no real control over. Hard mode isn't even that hard in general - you only have to survive for ten seconds on each room, and a bunch of these are still on the easy side since some of the discs are so harmless - but it is certainly stupid.
