Neat little game! Of course it has birds, so I was already sold on it.
I thought this would be some sort of multi-ending game at first (with multiple endings), but it seems like there is only one. A bit disappointed, but still great for a game jam! I like how you played with the window's size from script at runtime. First time I see that here for this jam!
Only real missing feature is some audio. Yes, there is one hit sound, but some ambiance and more sound effects would greatly add to the atmosphere.
Apart from that, good entry!
If you've got some spare time, come try and rate mine! 7 different endings, hilarious narrator and it also has a bird for the main character! Worth checking out!
