fun and lovely looking game! I liked the whistle being something the antagonist uses against you, and being a very active mechanic to when you can be out in the open. of course not everyone has made it an object the player character uses, but it still feels more unique in the way that it's used as an obstacle
I do agree with other people about the difficulty spike, partially because I did struggle for a bit to understand what parts of the level were dangerous haha! it was a fun challenge though and though I did get frustrated, it faded as soon as I managed it. very enjoyable! also this might just be me, but it took me a little while to gauge the range of where you can jump to. I get why it is limited the way it is, but if you don't get it right and only wanted to tap for a smaller jump, you just end up dying a little more than felt fun imo. I did generally do the fully charged jumps anyway so I was able to check my jump would work as intended, but I wonder if having the cursor change colour when it's out of range (before you press space) might make this feel a little better? again, could just be me though lol
I really loved how you combined the potential themes, I also really liked 'only one' and wanted that to win tbh (though I'm very happy it turned out how it did in the end) and I think the idea of the one action was super creative and cool! and again, looks fantastic and polished, you absolutely deserve the praise you've been getting :D
