I've made 1 level for maybe 6 months ago, and it turned out to be overloaded with stuff so it even lagged on some points. But screw that, I made a new one. It turned out to be light, not overloaded. And at the beginning, it's also this 50-50 (60-40) risk of failing on a note block. So try a several times, just to notify ya'll, it works more than it fails ;).
And about that overloaded automatic level, I added it to the IPS file too, just for fun
(But at the right side, while the main level is on the left side)
Everyone, feel free to download it (This is also my entry) HERE
P.S. The level I've uploaded here, can also be found on YouTube. But I did a small configuration at the end of the level, and it is not shown at YouTube.
P.S.S. Lol, haven't been on this site for weeks :p
