Really superb game design. My hat is off. The symmetric effects really made me question which choice I would make. Personally I'm not sure if I liked the purple cards but I do like what they tried to do. I think a choice with all purples would be more preferable. Or perhaps a single slot for an ability which can be overridden further down the line depending on which passives I chose. I think some cards which changed firing pattern might spice up the dodging a little. And some different enemies with larger health totals may also be a nice edition.
The art and sound married beautifully. This is just a really great entry. Thank you for making this.
