Update post GMTK Jam

Hi there,

The Jam voting session is over, so here is a very very small update:

- I fixed a bug where when the game is over while the croc is sleeping, the sleeping sound does not stop.

- The main screen has changed a tiny bit, and I updated the page cover image :)

Known bugs:

- When you type enter while using one of the sound slider, you can't recover from that and have to relaunch the game!

Please be tuned for more updates, i plan on making quite a few changes !

Thanks to everyone who played the game during the voting session :)
