This is a solid base to expand on, with an interesting, but maybe “cursed” mechanic of two axis gameplay. Cursed because you need to figure out how to solve the problem that with each draw, half the cards are basically dead draw due to focusing the wrong axis. Some ideas:
- Spell that switches all axes to X or Y
- Relic that makes you draw a card when playing an X axis card
- Power that makes axis X cards cost less energy
- Combo effects: playing X axis card makes the next Y axis card this turn more powerful, or free
- Stance switching: playing a card of an axis makes all cards switch axis.
Particularly more draw would likely be important for this mechanic.
Overall I enjoyed it, though I would have liked to see more content. Understandable if you ran out of time, it is a really big project to take on for a game jam :-)
