Help I can't do the Bug Squasher achievement because I have one spider missing at the clockwork world. Can't seem to find it anywhere

Why doesn't this have rebindable movement keys? How can I override WASD?

Before exiting the game, an advertisement for Figment 2 is shown. I understand why it was placed there, but it plays unexpectedly and at high volume, ignoring the volume settings in the game. This is a very terrible idea for all those who, like me, play with headphones, turn down the volume of the game, and get a blow to the ears before exiting the game. I hope the developers will notice this and do something with the volume of ads....

so, i play this game on 20% master volume. but when i exit the game, it plays a niiiice little trailer video. and as my ears start bleeding, i realize, this one is not affected by the master volume control. please fix this. it actually hurts ears. alot. and i am pretty sure, part 2 wont be about fixing ears....

I'm very tired. I've reached the end of the game, now what? The final boss is too hard for me. It has nothing to do with logical thinking. I'm very frustrated because before this game was brilliant for the most part. I will never pass it because there are no green additives after every batch of purple puddles. Or the option to skip the last boss so I can see the ending in Polish....
