This game captures the old school platforming feeling so well. Having said that, the game is nails. If you aren't prepared to put in the work to find out how every god damn thing in the game can kill you then don't bother.

You'll easily die 100s of times before seeing the ending and 100s more before seeing the true ending. Being a Rogue like, this is to be expected.

There is no permanent progression and therefore knowledge and mastery is what keeps this game engaging and fun. If you don't like the core gameplay loop, you won't get much value out of it.
