Pretty good port of an old classic. Props for actually adding the new 2.2 abilities, although I think this could still do with some visual tweaks.
Watching Metal climb up a wall by just hovering next to it, or shooting an invisible projectile while standing completely still is a little jarring to watch. I think some custom sprites for a few abilities could really make it feel better to play, and maybe even tweak some vanilla abilities to make em... well, usable. I'm looking at you, Telekinesis.
But other than that, pretty good overall, welcome aboard.
For sprites specifically though, that's mostly my lack of skill. I just preferred copying sprites over to making ugly ones. I would probably update this with some sprites if I got someone to help with that.
Thanks though!
