Dom, great to hear from you and always appreciate your feedback <3!
Each world (there will be 6 in total) has its own parallax background. I haven't thought to approach an animated parallax yet, but that will have to go into the idea bucket for improvements. Right now, I am trying to keep scope low so I can see this thing to the finish line.
Not much depth to the poop mini game other than tilting the Playdate right or left and then hitting poop button while above the target. The target can spawn on either side though. That is a good idea with change of speed.
I haven't seen the mechanics of the classic Mario fireball, but I will look into that :).
I really want to give this game enough meat to feel catalog worthy!
