I strongly recommend you play the original first, this is a Hardcore Version. Every level is possible, I checked. This is still in progress, I have only hardcore-d part of it. After like level 70 then it will be the regular Controls: M-To Mute music S-To Start music again P-To pause game R-To Resume B-To go Back to the start of your level Some levels will seem to be impossible but they are not.
