For what content is here, it's all extremely polished. Game feels good to control and responsive to actions, pixel art is very cute! I only wish this was an arcade game i could play at my local arcade!
I would recommend a bar on the left or right of the screen to tell players how far up the mountain they've made it. maybe milestones and different zones could be included?
The hard cut to death screen made me actually laugh out loud. Keep it up yall!
