This is a decent little game. I liked the idea you had about trapping birds in the pipes. I found it odd though that I couldn't use W and S, and the arrow keys stopped working for me near the end of my first session.
Yeah, you can only control the pillars with the arrow keys right now but we will add the W and S keys in the next update. The issue with the arrow keys not working is extremely rare and should be fixed if you restart the game but we will work on resolving that. Thanks for commenting!
