Great game, I loved it. I love how you found a way to make an already accessible genre even more accessible by removing movement and still keeping it fun through cards. I love how absurd it can get. But there are some issues.
1. Get this on a storefront like steam and charge for it.
2. Change up the controls so people can double click to activate cards and right click to remove.
3. Find a way to make the game harder for the late game. Possibly limit how high some stats can go because as is it's way too easy to go for 99:99:99. Maybe increase enemy scaling after the 30 minute mark. Maybe find a way to encourage multiple rounds over long rounds to help respect player time and investment more.
4. Add a killswitch that'll just off your character so you don't have to play until you die.
5. A stats screen would be nice so I can see my kill count as well as stats like crit chance.
You have something really special here, thank you for making this.
