Some Gonta thoughts
On one hand it would've been sweet if Gonta had a pet bug in the game like Gundham had his hamsters.
On the other hand then we probably wouldn't have "Gonta finds nanokumas" mini plot plus Gonta wouldn't feel as lonely and as desperate to belong as he feels in the game and probably wouldn't have his reverse growth arc of him deteriorating psychologically to the point of agreeing to murder.
