Vita version corrupts save games on floor 6 or higher

[aknight2015]

For the PSVita version, every time I save the game on floor 6 (Aliens of Gold or Planet Strike) or higher I can't reload the save. I get a corrupted save file error.

Unfortunately I can't help here.
The PSVita port not maintained since v1.1.10.

This also happens on my M1 Macbook Pro. Could be relate this issue?

Probably, but I don't think the developer is developing this port anymore.

I can confirm this, but for me it's floor 7. I even tried entering floor 7 and returning to floor 6. The savegame does load but when entering the elevator and selecting floor 7 it will crash.

I also encountered another problem on Mission 6 floor 6 where after the purple keycard door there was another one requiring another yellow keycard which is a normal door in the Windows version (see attached image).
