I liked it, congratulations!
The environment is interesting, and the visual design is very nice. A background ambient music would have been great; listening to noise for so long was tiring. Also, a minimap or a running feature would have been good because I kept getting lost on the maps. But of course, we shouldn't forget the jam's time limit, I'm rating the game while keeping it in the mind.
Overall, I liked the game. Congratulations.
