Hey! I'm glad you found the game even if it was by accident lol!
Thank you for your feedback. We're going to have better onboarding for the demo version (when we release it) as well as settings! The prompts that pop up tell you how to do it though it needs a better way of implementation (the tutorial) so I understand why you didn't know.
When you say crafting a weapon, do you mean when you selecting the one of the boss's abilities (the 3 card screen)? In this build you can't craft weapons but in the full and demo you will!
