The game is pretty good, and you can feel the dreamlike feel. It's quite peaceful, and the bird models and their walk are somewhat cute.
As Rico says, the sound just needs some fine-tuning. Regarding the bug, it seems to be a logic problem in the code. The first text doesn't disappear, and the second text bugs. If I press E again, the second text disappears. So I think it's just a matter of reviewing the code flow.
The other bug, where the birds get stuck, is only in the pigeon room. Specifically, on the platform in front of the puzzle, any of the birds get stuck with the invisible wall and can't move, so maybe it's just a matter of checking the collisions in that room (I think).
The settings menu works perfectly; the only problem is that it only offers borderless window and full screen modes. If I set it to window mode, it returns the borderless window.
I hope to see a little more of the game (if there is one)
Great experience! 🥚
