This is my submission for the 2019 GMTK Game Jam. The theme of the jam this year is "Just One", so I made JELLYHEAD, a sidescroller game that uses just one button!

Man that was difficult, I did manage to beat it though. I suspect a lot of players will not get past the first spider or the spiders combined with 'falling things'-obstacle.

Also, those blocks that turn on/off when you jump were confusing. At first I thought that they changed based on time intervals.

The obstacle that slowly disappears and reappears was pretty neat. It made for an interesting level, in which you needed to influence the level to get those projectiles across.

I think the sliding enemies on the ground are probably the weakest element I came up with. I'm glad you were able to get through the game!

I appreciate the feedback about the toggling platforms. I tried to design the level in such a way that players knew how the platforms worked before they had to jump over bottomless pits involving them. I wanted to avoid a patronizing tutorial or dialogue box that tells you how it works. Again, I'm glad you eventually figured out how it worked!

Thanks for all of your constructive feedback! I appreciate it!

Pretty clever idea and fun game, some of the challenges seem a little too difficult in the beginning.  The combination of the 2 hazards in particular.  I think there may be a memory leek there too because I got a massive slow down in that section and the projectiles started to bug out. I like the idea for the game, one button.  The character had a meatwad vibe too, haha nice job.

There is a known bug that I easily overlooked before submitting. Usually, for testing purposes, I program my games so that pressing the escape key will exit the game. However, the code I used to exit isn't compatible with the browser player and causes some memory issues. That might have been what you were experiencing.

I'm glad you liked the game! Thanks for all your great feedback.
