I have a new game and have a question about level design

Nice system!

In that case, I’d suggest you go for more 90s levels.

Maze-like levels I mean.

Or go for the more narrative levels (i.e. Half-Life).

By the way, you can One Unit Whole Blood (BLOOD and all it’s expansions) on GOG or Steam.

Good luck.

Feel free to PM me if you ever need help with anything.
