I haven't got to it yet! But if you want a challenge yourself try my Bowser's trial. 5 people tried so far, 28 deaths combined, it hasn't been beaten yet. You can be the first ;)

There is a huge gap between the levels posted here and playing the 100 mario challenge. I did a normal challenge yesterday and swapped out at least 50% of the levels by save/quit resume. I didn't feel like giving any of them a star. I guess it's the luck of the draw but most levels I got were indeed either a mess or the default level with more/bigger mobs added and a bunch of trampolines. Hopefully that gets better over time when all the messy and lazy levels sink to the bottom.

I haven't played much of the 100 Mario Challenge (or random levels in general) yet, so I was assuming this was based off of levels shared here.

Please try out my levels, guys:

Dark Souls-The Catacombs
Difficulty: Medium; Clear Rate: 6.00% 3/50

Beat. Now that was a rush!

In the latest issue of EDGE, Nintendo producer Takashi Tezuka spoke about Super Mario Maker’s unlock system. He told the magazine:

“This decision was part of our basic policy. We wanted the rewards to increase as you became more familiar with the game and to look forward to what would unlock the next day,” he says. “From our testing, we learned that if too much was available all at once then many players weren’t sure what they should do and didn’t have as much fun with the game. However, I do understand the feeling of wanting to unlock things earlier.”

Do you agree with him?

Made my first ghost house. Try not to get confused with the warp pipes! There's two ways to get to the exit and there are three 1-ups in this level as well. Can you find all of them?

I also put my past levels in MarioMakerHub. Check it out!: http://www.mariomakerhub.com/makers/Skha07

So I made a new level, hope you enjoy it, if not tell me why so I can improve in the future

Here is the code: 6359-0000-0073-9689

Something different, a short story about how it all started.

A quick easy stage, for once that clear percentage should hit the double digits on one of my levels!

I finished the easy version finally, well almost. Yeah it is still very hard. First I died at the sub boss until I saw the exploit. The jumping sequence was not a problem with the extra chances from the propellor head yet the trampoline jump to the vines kept doing me in. I can't get a trampoline to work reliably. Once it worked I couldn't get Yoshi on the blue shells in time. Next try I got the the end boss room but the thwomp stole the clown car and I timed out. Then a bunch more deaths by vines, however I was skipping the p-switch by then so it was a lot faster to get back. Finally at the boss battle again, defeated him with 50 seconds to spare, but somehow Mario would not enter the pipe from the blue shells. I got shuffled off going back and forth then couldn't get back on before the time ran out. Oh well, I consider it beat lol.

Pac man was a nice way to relax after all that.
