This game has such a good atmosphere. From the music to the look and feel of the game. Everything makes it such a good game to just be in, let alone play.
It's a platformer at it's core, and the platforming challenges are...well...challenging! In a good way. You probably will die multiple times, but the game doesn't punish you for it.
For a game made as quickly as it was, this is a quite good game!
