The controls don't feel good and the perspective is weird. Sometime I don't know if I will land on a branch or fall through it, there is no real indicator. The choice of a 3D world with a 2D gameplay could be fun but you need to make the platforms obvious for the player.
And each time I start a dialogue, it loop forever and I have to reload the page and start over without talking.
The gaphics looks good. It's a good start made in 48h, with some more work it could be a good game.
