Thanks for the comment, glad you liked it!
The loops are a bit frustrating, I had a hard time balancing the ant AI to work well in both low and high ant numbers. I also had to make them a bit dumber because I was running into performance problems. But I'm sure it can still be improved given some time :)
The last lava bit was done in like the last hour of the jam, I didn't even have time to properly test it, from the feedback I gather it's too hard :P
