To Firewall and bulbapuck: Awesome, thanks for taking the time to enjoy the ol' level!
As for future levels, I'm not actively working on anything of my own at the moment- too busy with school. I might restart Apocalyptic City, the environmental level I started, during summer vacation. No promises though.
I am occasionally producing tilesets for Boot Stamping on a Knytt Face Forever by JCGrim. Go check it out on the forums if you want, it's coming along slowly but surely.
I remember this level it was truly epic ! In one of the earlier versions, though, I remember a very original challenge on the way to the "bad" ending with those red things that follow you at high speed, which was taken away to give a more "sad" feeling i suppose (what with it being so easy). Pity. Also at the start if you jump over the powerups and then down the hole, you are stuck forever .
Actually, if you want to play that bit, I made it into its own separate level called Monocromatica Grotta (The White Cave in Italian). You can find the thread
here for the download.
As for that bug thing- LOL. I didn't know about that one. I assumed that players would automatically take the power-ups, not actively avoid them! Thankfully, that part's at the beginning of the level, so it isn't too big of a deal to just restart if it happens- they'll know what they did wrong.
