Unusual, frightening and already uninstalled Rated 3 out of 5 stars
Minuses for sound effects (should be off by default; when I first heard them, I quickly closed Fennec), brutality (beetles are a helpful part of ecosystem; and you portrayed the beetles as blue funny creatures which don't deserve destruction at all) and slowness (on my device, at least; and I have only one tab open in Fennec and bare minimum of six windows which aren't CPU-intensive at all).
Plus: for thinking out-of-the-box and unusual concept. Fennec wasn't designed for playing games, but you put a game inside it.
In my case, the bugs weren't interacting with the page; they were flowing on white screen, and only after I exited the game, the page returned.
Thanks for the rating and the funny comment. :)
Can I ask what device were you using?
