A few suggestions
The bugs move too fast towards the end for you to even stand a chance, therefore the game doesn't even last that long.
There's no real skill or strategy involved since the bugs move too fast.
The only thing you can do is button mash. Any combos you perform are flukes.
The webs that drop from the top of the screen are barely even visible because they're so thin and the bugs cover them up half the time. They stun you for too long as well, so you're screwed if you get hit.
The special attack shouldn't fail as much as it should - it failed 4-5 times in a row for me.
If those parts were improved upon, then it'd be a decent game.
