Didn't like it at all.
The text on the main menu floats off the screen.
Kobold feels very hard to control. But it's fine. Double jumpy wouldn't have double jump if you jumped out of edge.
I don't know if there are more levels than 2, but I couldn't complete second one. Double jump just can't get to the finish. There's no way.
But other than that, the concept is good. Yet game needs quite a lot of polish. Wish you all the goods to make it a better game
