New Game Design/Gameplay needed for dealing with Enemies in future games

[Lazoriss]

A sneaky monster would be difficult to program because you'd have to spend a lot of time balancing the encounter. It'd be too easy for it to end up frustrating or tedious, especially if you end up dying a lot. For an indie game company, that's a lot of effort for a single enemy encounter. Although it might be find having a few memorable and well-done enemies, than just a bunch of short encounters with a mixed bag of monsters.

One game that does use super sneaky monsters is Monstrum. It's actually a pretty scary and fun maze-ish game. The map is randomized, as well as the monster you get, and they're all pretty well balanced out.
