First of all. Thanks for playing! 👽
Secondly. The version up on itch.io is a little out dated. I have the game coming soon on Steam!!
As for your bug, do you have the purple beam attack at this point? In the old versions you could damage boost your way up to the snake boss without unlocking a way to kill him. I have made this impossible in the newest version.
I'll get you a steam key and you play the most up to date version if you like? I'd be more than happy to hear your feedback!!💪
