itch.io

I just realized I forgot to include some important details in the instructions sorry XD. Basically, I forgot to mention that you need to enter the special mode, specifically in level 2-1. You have to go to the pit with both the first and second players: the first player must have 6 lives, and the second one must have 9. After that, it should unlock. As for the intro issue, I think the problem is with the name file.  I'll try to fix it tomorrow.

I have downloaded the game directly from itch.io, and the secret mode and the intro should be working properly.

yup, all the stuff you reported me is fixed

I'll check it later, thanks

fixed

could you specify how the error occurred and at which level?

I'm gonna check it later

It's a bit hard to reach it, but not impossible. I recommend you to start running after you pass the lava pit and jump twice without slowing down
