Hey friend, I just had a great idea for your game today randomly (possibly scope creep but what's life without it lol) a way to solve your most requested feedback (the progression spine) you should add tournaments or events the player can sign up for/or automatically happen and it would be wave based battling to test the players collection and the day to day battles can be to hone their skills for better and better tourneys.
I like the idea :) you mean " single player " tournament right ? ( I am not sure yet how to make async multiplayer 😅 ) Like a series of fights where we cannot change our team, ( but still reset between fights or not ? ) and / or for waves, in that case I guess we don't " reset " our team, so we need to last as much as possible or something ? I like these ideas. Could be fun indeed ( and more challenging ).
