YO this is really good, it scratches that deck builder itch. 😁 I'd love to see a full version of this! You clearly have focused on what was important to make the game fun and playable in the short time (I hear you got sick, I hope you feel better soon!). I kinda love the ms paint drawings anyways lol.
I did find the most difficult setting a little impossible, but I was trying very hard to get mouse her plasma so maybe thats why. I think the enemy just before mouse ramps up their damage a little too fast perhaps? Or maybe I just need to git gud 😫
Also, I'm mad that I've made a progression/map like yours before, for a previous jam, and didn't think to pre-make it as a set map. I built a whole randomiser for the jam, where I could of done something else with the time😭so well done for not doing that...
