Really really good! The background music is really soothing, to the point I didn't even notice 50 minutes passed while playing this. It really captures the feeling of a ominous, but cathartic dream! I really don't think this game would benefit from being longer, I think it's better to keep it short and sweet. But I will definitely keep my eyes open to any other games you publish, if you are planning any!
(The only sad thing is that, somewhere along the way my penguin friend just disappeared, so i got worried i did something wrong. But I'm pretty sure it just wandered off frame or something ^^')
