Hey man thanks for making this!
I tried to get past the first area for 5 - 10 minutes but i wasnt able too! this might be a skill issue but i think a good suggestion would be too create a small section at the start thats dead easy to get people to understand the jump mechanics
I found a bug where if you jump on a slope it then locks your jump to that direction all of the time, not sure why
This is fantastic for a first attempt, well done!
