Unfortunately there isn't much beyond that in the game. The bag-of-bugs has a couple interaction as well as the "Weird Ball" item you can get as a large prize. I'm sadly, not able to work on the game any more. Burnt out and the code is just to much of a mess.
Yeah, you've basically found everything. I have actually published a few new things to my page. Mostly just small toys. Dunno when/if I'll have the time and energy to work on something bigger. Tho, perhaps, not as ambitious as I was with CC.
