Other wilds as already suggested Is a must play. But a strong second contender for me Is cocoon. Logic/environment puzzles, with no hand holding in any way, you have to figure out everything but the level design Is sooo good.
Honorable mention for Tunic.
This may work if the developer is a possible client too like in this case. But I feel that’s the exception.
Do what the clients want and not what developers, designers or management want.
