I just had a quick go at Zloxx II - no issues to report. (windows)
It seems quite polished and fun. Nice work, Nexus!
Controls felt good. I kinda got stuck at the first disappearing blocks section in 1-2, because I didn't realize you could change direction in the air.
But then again, I am far from a expert platformer.
Music is great. Sound effects are good for what's there, but maybe could use a few more, say for landing, hitting walls, or killing an enemy.
Thanks for sharing.
