You came up with a good concept, but as a game it's spineless. When playing, you simply place your mouse on the first enemy after the doors and poke until everything except the doors disappears. If there is a corpse under the cursor, you also move it.
I would like more file explorer mechanics. Enemies that can only be killed by highlighting (and an accompanying item that adds ticks to things for easy selection), renaming, for combination locks, for doors, a function to display in a new window would be perfect, and of course ini files responsible for icons that can be hack. Perhaps a search would be suitable for the game, with a limit on files, bookmarks, portals with shortcut functionality, the ability to move by a line with an address (But only to one position) and secrets associated with this line.
