Sand Runner

Sand Runner is my first Jam game and I program just for 3 months. It has simple randomly-generated terrain, menu and two threats (enemy looking like super meat boy and spikes). There are bugs in random terrain generation. I would be happy for constructive critics or tips. I programmed this in Game Maker Studio 1.4.

Diary:

Friday,6am- What?! It starts tomorrow?

Saturday,6am- Come on! That isn't the theme I wanted. Let's do platformer around the world.

Saturday,2pm- Running late! I can't make all five levels. I'll make it random!

Saturday,6pm- All done! Just the play test...

Sunday,6am- It's finally working! I will celebrate for three hours!

Sunday,2pm- Running late! Again...I shouldn't celebrate for three hours. So much time lost...

Monday,6am-Some nice background...

Monday,2pm-Some nice foreground...

Monday,6pm-Sounds...bad. Ok. I'll go over that.

Monday,7:30pm- Submitting... But how?! Finally...

Tuesday,3pm- OMG!!! There are so much bugs... And this could be really easy to repair...

But Sand Runner will be back as Biome Runner Ex... maybe...

Controls are: W for jump, shift for fall (faster) and space for punch. And escape for pause or quit.
