Author Topic: platform.bas - an attempted QB64 clone of Mr Jump S (Read 8162 times)

FellippeHeitor · « **on:** February 21, 2018, 02:11:23 pm »

Here's the current state of my clone of Mr Jump S. No difference in gameplay, as I've simply restructured the code so it's prettier and easier to follow.

Ah, but now you can now jump with the mouse button (click on the game screen).

ESC resets the random level.

This is taken directly from the latest commit c6521ab.

Cool! Did you code that? It reminds me of Nintendo Mario.

Pete [:)] Maybe now some time to enable smilies?

Definately had fun playing that one for a few minutes. :-)
