The fourth game in The Walls. The first two games had the same upwards wraps, but these are upsidedown! It is kind of the same thing, just a different layout of gems and walls.. took me 11 minutes on the last attempt. Overall, over an hour of attempts.
update aug 22: removed half of the gems for being unnecessary, added 2 checkpoints, made 2 jumps deadly, and hid a gem in a wall before 2nd checkpoint.
I also added a portal at the end. Dont trust the portal. It will most likely end badly. No gems are in the portal, only death.
