Um, that does sound kind of like a roguelike
😀
Was it more of an action game, or stealth, or puzzle?
Any specifics about the graphic style, pixel art or just sort of "standard" graphics?
It sounds kinda like Replikator:

But that one doesn't seem like it's actually gotten a final release yet, so probably not it.
Maybe Heat Signature?
Heat Signature is a game from the developers of Gunpoint where you break into spaceships, make terrible mistakes, and think of clever ways out of them. You take a mission, fly to the target ship, sneak inside, and make clever use of your gadgets to distract, ambush and take out the crew.
