I really loved your project! Thanks for taking the time to check mine out :)
The general flow for cards is:
- Place attacks down
- Place modifiers on top of cards
So something like, `Burst-> Twist -> Link` would shoot a burst of projectiles that have a slight spiral to them, toward the player. Another nice property of the modifiers is that they stack. Most scale additively, and sometimes multiplicitively! For example multiple twists at level 3 will create a really tight circle around the target. I say `target` in this case, because homing and link exists, and its possible to get things orbiting around the player or enemy.
There are a lot of hidden interactions and mechanics when you start inverting cards (Faster becomes Slower for example)
To invert a card: Collect 5 pickups, then drop a card on the black circle that spawns, you can continue levelling cards by dropping already inverted anchors at the inversion anchors.
Beware that some inversions are very literal.
