Added a bunch of stuff in a hour, and kept the original <3hour build for the gamejam, improved physics, the birds now have differents speed, jump height etc., also tweaked graphics and added choice between 16x9 and 4x3 resolution. The ini file were also updated, but most likely will remain the same through the development, so for each update you will be able to just place it alongside the .exe file to keep your progress n stuff.
As always, enjoy!
