Really cute game thats telling an interessting story with a nice kind of humor :-)!
The leveldesign is really nice with well placed checkpoints. I also like that the game is slowly getting more difficult.
May I missed it but I really would have loved to know how the "double jump" was working. For a long time I thought I just have to die enough and have to see all dialogoues until the game ends - because I couldn't jump above that one box. Then I wondered why the jump sometimes works and sometimes not. After a lot of tries I noticed: it is more like climbing and I need to be close to an edge. You really should give there also kind of a tutorial because you was close to loose me at that point.
But I have to point out again that you did really good on the story. I wanted to know how it goes on and thought "That can't be the end of the game! IT CAN'T!". Onlyl cause of that I tried many times to beat the level and in the end I made it.
Very nice game!
