Hello, and thank you for your very detailed response! Since you wrote out so much for me, I feel it's only fair I send you a response back!
First of all, I'm happy you at least partially enjoyed our game! This is the first time I've made a card game, so there was a lot of learning going on in this jam, and not as much time for testing, haha. Understandably, there's a lot of things in this game that are rough around the edges (both from the viewpoint of you, the end user, and me, the programmer). Having the deck more skewed towards movement than attacking is definitely something I was aware could be a problem, but I couldn't fully tell how serious it was without more testing from other people (like you!). I appreciate you have the same mindset I had, that having too many attack cards would make defeating enemies too easy, and I also wanted to include multiple copies of the move cards to ensure the player could actually have decent manoeuvrability around the board and not feel "stuck", but in retrospect, there are not that many attack cards starting in the deck, which makes them show up infrequently. The initial justification for this was that you'd add more attack cards to your deck throughout the game to even out the balance, but of course this devalues the cards which don't either attack things or draw deeper into your deck.
Balancing all the cards was also not exactly something I had a lot of time to consider, particularly for the character cards... (see: Marisa. She originally didn't even discard anything LOL. The discard thing was sort of just thrown on last minute when I noticed that she objectively did the job of nearly every card but better.) The character cards are all meant to have really crazy effects so they can't truly be balanced against each other or the overall game, but there are certainly some outliers in terms of especially strong and especially weak.
Did you get to the last level (7)? Because that one had almost no time for testing and is honestly brutal. Our composer managed to beat the whole game though, so it must be possible...
The pencil line art was indeed a stylistic choice on the part of our artist, meant to evoke the ending panels from mainline Touhou games.
Thank you very much for your kind comment!
(Also I don't play roguelikes either, I just like card games lol)
