Congrats in completing your first LD entry!
Ok, on to the feedback. K works as a double jump, so you could just make it a double-press os Space. No need for a second button input there.
Also, when you get to the first obstacle, the purple grass/spikes, it was too close to the ledge. It would be better to introduce such an obstacle in an easier-to-avoid place first, then do something like this later on. The jump is too high and across a large distance, making it hard to tell where you'd land. Most of the time I'd fall straight into the trap.
Still, good work on your first entry, keep participating!
