Fall through floors is currently being considered as a powerup, for two reasons.
1. It's a bit powerful, given the nature of the game! It was ok in NeonPlat, but here it's a bit more strategic.. .. I think! Assuming I can get the level building to work properly
2. I've still not decided if the bottom should kill the player. In the current version it does, but the end result may differ! (really making this up as I go!)
Jump On Enemies was the most hated thing from NeonPlat 2. I've taken him out, but if folk like him, he may return!
Bricks to Destroy, floors that collapse, moving platforms, and a whole bunch of other floor/wall/roof tile items that I've got written in a great big list, on my desktop, that I've also not added yet. Loads to do!!
As for the powerups.
I was kinda thinking Kirby-ish.
The ice (I'm still not happy with the Ice sprite!!) freezes the enemy, the Flower things fling at the enemy, but the sphere doesn't quite do much yet. It's planned to be the powerup item.
Once baddies are hit with it, the sphere becomes a powerup, based on what it killed.
... you can chalk that lack of addition up to my laziness
