I completed the demo.
I think you got the 80s saturday morning cartoon vibe right. The team is perfect and the characters you get to meet are interesting enough too. Besides overall the animations in as out of combat range from good enough to cool.
The game is fun. The roster of cards is good enough for a first mission, and I thought they were balanced well, with cards you gain all better than the ones from the original deck while the ones you get seem of similar power and choosing between the 3 is always an interesting choice, that's how I like it to be.
I didn't get the Focus nor the character bars.
Overall the game is very stable, I think the only bug I got was the stunning stars displaying on the bottom of the screen instead of above the enemy. Sometimes I wondered if the enemy turn went longer as it went but it was not that clear.
On particular cases the enemy AI would deserve to be better in my opinion, for example I think it should use its +2 something for 1 energy before using the +1 ones, it's weird that it doesn't. Sorry if I'm wrong but I think that sometimes it uses an attack card on a stunned enemy and that's weird too. However don't get me wrong, I think that on more regular cases it's perfectly fine that it does more random things that doesn't particularly seem optimal though, I don't think it's a bad thing.
My only caveat at this point is that overall everything is too slow, one way or another I want to be able to play this game as fast as I press the buttons. You should be able to skip the transitions between screens, speed up the enemies' turn and probably speed up some other things I can't think of by mashing the Left Mouse Button.
