I managed to "beat" it (I didn't get any text, and when I delivered to the blue guy he just burst himself out of the game window hahaha *pic proof * ) ! I felt something like "I wanna be the guy" game but healthier hahaha, really nice game with low "budget". It's a bit buggy but that make it special, when I entered the mountain I felt like the old atari games :)
(The theme inspiration doesn't match the game I think :p)
