Wow this was a very in depth analysis! Thank you for playing the game!
The mouse being registered as a confirm button for the UI is a bug! Not ony that, but not being able to call the pause menu while in game is also a bug!
We wanted to make a more ludic way of showing the story to the player, but unfortunately we only had time to put it on the game's page But basically the birds were stealing all of the bananas, you were right about making them more evil :V
Thank you for the feedback on the music!!! Me and KlebO worked around the clock to make the soundtrack!
We kinda messed up the controls... Using 'J' to attack is way more confortable when using 'WASD' which we never mentioned in-game.
You have probably found an infinite loop at the end, not a crash, which caused the game window to be frozen, i am EXTREMELY sorry, we never found this during testing...
I still hope you enjoyed the game even while encountering these issues...
