I usually translate to "between 25 and 60 FPS" when I encounter the adjective "playable" but an unexpanded A500 seems way too underpowered to match this definition for these two games.

If by "playable" you mean "reacts to user input by modifying the visuals" then I would be less surprised.

Does anyone know how the coders achieved the very nice [ Show youtube player ] on the Master System? I assume that they are relying on tile-based techniques but if not then the effect might be transposable to an OCS Amiga. That does not exactly fit the Doom-like definition but that is reasonably close given the hardware.

If the same technique were applied to the others mentioned, they would've been faster as well.
I am not sure I understand what you mean by "to only parts of the palette depth", could you elaborate? This definitely seems interesting but I cannot wrap my head around what it means technically in that context.
