Yeah the CEO is the end. What made it feel buggy? It should have some final text then take you back to the menu.
And yes the cards are rewards to help you beat the following encounters. Not amazingly balanced as originally the idea was to have multiple paths that have unique cards so that you'd have to play multiple times to collect them all. And actually my team mate designed a bunch of different cards that are akin to actions rather than emotions, and under that system aspects would be what elements are now but it allows for a lot more cards without being confusing. There's even "spells" designed that are like single turn buffs. It was all just too much to implement on time! But post-jam I'll try and fix all this! :P
There's definitely exploits, haha!
Thanks for playing!
