I'm not sure if I got to the end as there was just emptiness after the second guard. It actually took me a couple of tries to pass through him (which is good!). The slime is cute, shame the game has no sound effects (you can get some free sounds if you google it).
My advise would be to look into the slime movement. You get a giant boost when jumping off of corners and it doesn't feel intentional. It makes it very tricky to control because of it, especially since you cannot control the slime while in the air. I jumped across half the level right into a guard a couple of times.
Also, those dwarves seem pretty violent :P Overall, not that bad for the first unity game!
