Well done on the game. I got 31/50 fertilizer before calling it a day. What would happen while playing the game is that I would lose track of where I had been and as such struggled to find more fertilizer at certain point, spending minutes just wandering around. Its also frustrating that in some sections you had to go in blind. Realise you missed stuff, and had to backtrack. Maybe a fast travel system to explorer places + a minimap would solve these issues.
On a more positive note, you got a pretty good feel on the movement. I liked the look of the game as well, and the music was nice. At some point you also introduced differently shaped scaling object, which were cool, but also a tad confusing, since it looked like it was scaling but moving instead.
Overall well done, it is a neat game, but the open world concept did introduce some challenges that weren't quite resolved in my opinion. Congrats on your first game, hopefully this feedback is of use!
