Ohhh this is a great game, I understand that is for a Jam and the time is just for a "demo"; but has potential to improve, the art is so cool I love how is not pixel but not vectorized, is just painting!!! the music is so relaxing and the history is good finalized!!!
now some critics (ok you make many many in short time, but is some pretencious project, so... it can be better if...) the map is so big, it requires more surprises to dont be linear; the music is great but efects... voices maybe... are missing; the places are good good draws, but are repetitive, place A = place B... this kind of games can be very hard or very easy, in fact of resources balance, ok it cost a lot of testing to find correct values, for me was easy in difficulty; I love how the characters talk about theyr past and how earth sick slowly, theyr goals in life, etc; but some thing game developers we dont has very good is the literature skills, to put drama, life, strong individuality and personality in characters, it is a common fail we have; and your game need, need improve that at future.
Finally I congrats you for the great work, in my mind I think in the tree of programing, state machines, etc hahaha its a cool project.
