This is a wave Engine I made with added gravity portals. Speed portals and size portals will come in later updates. First project of May :3 Any key works For creating a level you have to put each part of the level in a different costume instead of shoving it all in one costume. If you want the hitboxes to be more generous you can slightly shrink stuff to make it more accurate. For the level hitbox sprite copy and paste all the costumes from the level sprite into the hitbox sprite IN ORDER and remove any gravity, size portals, glow, effects, ect. Or you can draw each part of you level for a more cleaner hitbox. I mean like in plain colored blocks or whatever.
