I had a fun time with this! The open world was fun to explore. I liked the ability to make your own surfaces to climb onto, it’s a neat idea! Collecting the hats was fun too!
Some feedback:
-My GPU was being eaten up by this game and I suspect it’s because the framerate was uncapped. (I was also getting some screen-tearing so this might further support this theory.) I think the game could use an options menu to set a framerate and/or enable V-sync. I think some lower end PCs might try to play this and have some issues otherwise.
-I was often able to see underneath the world when near a ledge or cliff.
-I saw some strange shadow effects from certain objects when the water was in the background.
Regardless, I had a great time! Great work on this!
