Very cool game!
I like the procedural generation aspect, it makes every run feel a bit different :)
Sadly, the game stays too monotonous in my opinion as you can only run away from the enemies and gather rubies to run away for longer, an upgrade system would´ve been a very fitting addition.
Still, I really liked the design of everything,the 3d aspect made it feel very special.
Hope you continue working on this :D
