This is a platformer featuring a cursor-centered light and platforms revealed "or not" by light.
The arrows placed are misleading, and following them exactly will make you fall, respawned at the last lantern you found.
In the 1st level (ahead of the tutorial), I could find the lanterns, but not the portal. The free floating nature of the level's design means that it's hard to find the correct path to the portal.
The mechanics of the game, however, are competently done. The failsafe recall system shows care and forethought that the game could break for someone. Thankfully, I did not seem to require this aid.
Continue to practice, and come back in January!
