kgmcneil,
thanks for answer)

im trying to remake with adding new things, looking as things already been in game.
Some items i added inspired Colony game, items don't broke gameplay.. I done playable alpha but it not done yet. on Itch can be downloaded.
Items like traps, walls and item delivery center. (works good if save at least one scientist)
In some cases scientists can use doors, heal station and can repair some items.

I don't know how to correct continue rescue theme.
In any cases all 10 maps is alternative, not required. Any completing map - is complete whole game.
And i remove bad ending with starting ship without fuel (i thinking without fuel ship cannot start)

I thinking about continue, and some objects already done.
Engine i created already have a new items inside game which can be free used in levels.
It's not present on any map Rescue.
acid, scafanders, electric fields, cannons,doors with keys. light switch (dark zone in rooms)

And i thinking open source is best method support old games. I release engine as open source on github for everyone.

Many remaked games like Exolon or Cybernoid has dropped their authors and nobody NEVER cannot continue their works, btw they use CLOSE code and binary only.
some of them requires DOS (!!)
