Cube Escape is better, and it's free.

Cube Escape narrative was disturbing, insettling, Rusty Lake Hotel is just weird, nothing more.

Also, to achieve 100% you have to perform a specific action at a specific moment. If you miss the chance, it's gone forever. This is especially annoying because many puzzles are quite nonsensical, so it's a lot of trial error but, as already said, you only have one chance, so...

Overall, it's a good game nonetheless but, again, Cube Escape was better.
