Hey, I really like the game, super interesting and fun to experiment with. That said, whenever I try to run it on Chrome it works pretty well until anything tries to lay an egg, then it freezes up and can't be recovered. =(
This is the log that appears when it freezes up: Creature '' laying egg.
Anyways, hope you fix it and keep up the good work! It's inspirational!
EDIT:
Have you considered adding scenarios? Like "you must consume X pieces of food before Y time/energy runs out and you can only use Z number of creature parts". Idk, I think the extra challenge would be great, just a thought!
Thanks for the bug report. I think I know what's going on and it should be fixed in the next update.
I've experimented with some premade levels when I was trying to figure out how to do the tutorial, and found that limiting the number of creature parts was more frustrating than a fun challenge. Something open-ended could be fun though — I've been working on the level editor for the race mode in the next update (spoilers) so should be able to start thinking about challenges after that. :)
