As I work in nature and organize adventures this resonated with me. Good way to add a story by adding those signs, worked very good and it set the feeling that there is a narrator.
Impressive level design. I enjoyed exploration, but the gameplay felt like a trap. I made many mistakes and it goes perfectly with the theme, but sometimes it just felt wrong, as you just placed a trap for the player without any tips to avoid the traps. It made me to replay the game many times and after a while it got a bit boring. Maybe checkpoints could be a good solution. Or change of signs every time you die?
I see you have worked a lot on the sounds and slipping on the ice was the funniest one. I loved that mechanic and that sound too of just falling. Some sounds were a bit weird, because there was some realism with footsteps and then some random sounds which could be spammed felt out of the realism. But maybe that was for the reason. Also I wasn't sure about those images after dying.
And maybe some optimization could do the job, because the file size can be scary for many players.
But Overall, I played the game many times and that's good! You kept my attention and the game was experience! For sure there is a lot to add, the same with my game, but for a solo developer I can just shake your hand and say GOOD JOB!
