Depends on the definition of cheating. Here are a couple of ways in which I “cheat”:

I didn’t have the skill to progress beyond 4BC in Dead Cells, so I downloaded someone else’s save file with all items unlocked.

If I hit a wall in Silksong to the point that it starts to put me off the game, then I look up a walkthrough to see where the nearest undiscovered bench is or where to fine the thing I’m looking for.

For any game if I end too frustrated by a boss, I’ll watch a YouTube video to learn the attack patterns and avoid repeatedly dying to learn them. This is especially true for roguelites where I may have to cross 3 levels to get to a possible chance at a boss, and then get killed.
