Shortcut bug fixed + input problem on Menus fixed

Hey there folks!

We fixed a bug in stage 2, where it was possible to get trough the wall frame without the strength powerup.

Also, we fixed the problem of not advancing in Main Menu and End Menu with Z or X. Now, if you press Z/X on them, the first stage will start normally.

And that's it. Untill the next devlog, and have a nice day!
