My only direct critique is that it felt fairly repetitive without anything to break up the experience. Maybe something like a second target to defend would have spiced things up just that little bit more.
A simple concept executed well with a super charming art-style. I think my favourite part was that once the big bugs showed up I felt like I had to actually work to keep them away, it was balanced pretty well in that regard for a 1 week jam. I'm looking forward to where you take the game from here :D
