Thanks for taking the time to reply. Most of these points never crossed my mind, since when you play your own level you already think the way you intentioned. Thanks so much!

Hey everyone

I've made a level, it's called: Mario's Puzzle Lair (1716-0000-00E4-D684)

I really wanted to make a Metroid like level, in the end it turned out to be more of a puzzle level though I feel that I worked really hard on it, since it's my first attempt on that style. Please try it out and give me critique. :)
