Great game, but can be improved
This is very well done. There are, however, some things that might improve it:
- A map. At the beginning I had trouble knowing where I was, until I walked through it a couple of times from end to end.
- The physics. Jumping from one place to the other was tricky at times. In the green boss I kept falling off the edge all the time. I don't know how to solve this, but you might come up with something.
- Collision detection. Bosses have a collision area bigger than the actual size of the image. I found it disturbing sometimes.
Also, if you make part 2 (which I really hope you will) you could implement a way of climbing also downwards. And footprints on the snow :)
Nice job!
