Hi! here's some feedback:
Players will be expecting to be able to speedrun/parkour in a world like this. Currently the pace is too slow because the player needs to run into a block before being able to climb it. There is no jumping unless standing next to the block which breaks immersion. The player can't jump between buildings or climb very high in this build.
I think adding the ability to free jump while not next to a block will really help gameplay :)
good work keep it up
