My newfound love of Panel De Pon has been leaking into my creative process,
How about Puyo&Pons?
So, both occupy vaguely the same color set and have similar rules, here's how I imagine it.
Puyos fall slowly from ceiling, Pons rise from floor
You move things with the Pon style cursor
When a Puyo hits a same colored Pon they stick together, causing delay when you try to separate them.
Pons and Puyos do not react together except for special effects.
If you eliminate a chain of Pons with a stuck Puyo, you get a special effect
Red: Explodes, eliminating Pons on 3 sides but leaves Puyo unaffected
Purple:Expands into giant Puyo, pushes other things out of the way, can destroy things near walls.
Cyan: Freezes into Icy Puyo, will slide quickly if flipped in an open space.
Yellow:Charges into Electro Puyo, reacts explosively with other Yellow Puyos or Pons
Green:Converts all Pons around itself into Puyos and vice versa.
Black:Sticks to everything like tar, makes things harder to move.
Storywise: A crossever of Panel De Pon and Tetris Attack characters with Puyo Puyo and Mean Bean characters,
also introducing Eggatha Omeletta Ovoida Robotnik as a bonus boss because why not,
she would probably fit nicely with Panel De Pon's artstyle anyway.
anyway, I don't know if this is a viable idea or not, I was going to poke at it in Construct to see if it worked out but I don't feel like trying to set something like this up right now.
