I really liked this one! The visuals r really pretty and fit well with the feeling the gameplay evokes (sort of solemn but also adventurous). It's insanely impressive that you got world-gen working in 3 hours - doubly so considering that it still felt like there was a pattern to what paths lead to progress vs dead-ends.
It would be nice to see some more visual variety as you descended - I think for a title like this the reward comes from being able to uncover more interesting details in the world as you descend. New areas, oddities, geometries and so on can vary the descent enough to make each playthrough an enticing mystery!
Additionally it might be nice to be a little more forgiving about dead ends. For example - maybe the MC has a super-jump they can use a limited number of times to get them out of tough spots (which also requires the player to use skilfully in order to escape). Though maybe that would be antithetical to the jam theme ahaha.
Great job on this title!
