It appears to have been made by a single, creative person.
While it could definetly benefit from some polishing on the tokens, cards, and enemies.
The basic premise and idea is all there.
Most importantly, this game is fun.
That same timeless sort of fun like old sonic and zelda games.
I think adding a donate option may surprise you.
Unless of course you entered it into a JAM.
For example the "Mental Health Jam" is for games release from now until October i believe, and requires a made game that isn't a commercial release, to qualify.
Just wondering if that is what you are going for.
I've been working on a collection of drawn Tarot deck cards and i will take a look into making several cards with images, which i hope you may consider using. Assuming you can edit the title and text into the design.
