It's a hard platformer, but once you really get used to the controls the biggest difficulty becomes to know what to do on certain levels. The death animations and blood on the scenario after dying are less brutal than some levels. The simple story, nice music/sounds and great gameplay make the game really fun. Not a "game of the year" but this was never the intention of this title, it's a good combination of fun, simplicity and difficulty. Running on Linux, with Wine and Wayland, I've notice only one issue: the game completely freezes when it's window looses focus, regardless of any options on the settings.
