Well, there is some issues that I have noticed when I was attempting to use your game.

1 - The music would stop playing on certain levels, and wouldn't come back after that level was played; a restart of the game was required.

2 - The keys on the Level Constructor aren't working, as if I had to pre-set the controls to use the Level Constructor, just like the game. *the default controls are set to nothing so when one attempt to plays, the can't do anything except fix this problem :P

Now I don't know if this is my computer or... yeah. I want to create levels again, but I don't know what the problem is.

Haha, yet another level that I created for you guys to enjoy!! Here is a little bit about the trouble with this level. So this level is based on a horizontal layout, and I needed a way where a player wouldn't be able to cheat and just fall to victory. So I devised to use lava platforms, which had random lava placed throughout, however, I noticed with the placement of this lava, the game lagged horribly, so thus I replaced ALL of the lava with death pits and color coded the course. So here is the official description of this course.

Welcome to Skyholder!! Where you're enemies have trapped you within the realm of the sky. Since you're in the sky (of course) the sun tends to get a little... how should I say this... HOT. And you must avoid touching the red bricks at all costs or you will die instantly from the heat that the bricks are giving off. Travel your way down the course, until you reach the bottom where you will find the key, and the door to freedom being guarded by 4 guards who don't have any patience, tolerance, caring, or IQ for that matter.

Please enjoy, Skyholder! 

A new level for you tastes :P

Pillars of Doom!

One thing that you probably should be aware of is that an Executable file will not run under Mac or Linux, which I have Mac, but I'm simply able to run the game by downloading the original source code.

Yes, I was one of his "beta testers" of this game. I remember the game to be quite difficult and challenging when he had me first play it. Now, the game has become a little easier for me because I got used to the controls and what not.

However. I will say that this game doesn't quite resemble Super Mario Bros. (at least the original) that much, because if I play your game, and then immediately switch to Super Mario Bros., the control feels different, as if Super Mario Bros. is in slow motion compared to your game, but that's just my opinion.
