Problem: boring game

Making progress. Currently, I have a problem... I think the game is boring. Maybe I'm wrong. Looking for feedback. 

Some ideas I may implement

• remove silver entirely and add active skills during gameplay
• add an xp system for each character
• add cards that you can choose from each game, they're also upgradable in the menu

I'd rather make changes based on feedback because knowing me, I could add, remove, and tweak the game for months.
