Are the achievements broken? I finished all levels but didnt get "All for this?!" I finished level 1 while using all traps and towers but didnt get "Trust me, i'm an engineer !" I finished the tutorial two times without shooting but didnt get "How do I shoot ?!"...

Is it possible to change this crazy move settings? Q/S/D/Z? How am I supossed to play like this? With third arm below my left armpit?

... ooh there's achievements?

Is the achievement "How do I shoot ?!" broken? I can't get even after clearing it 3 times now. I haven't try to get "Trust i'm an engineer !" or "They'er everywhere !" Do i need to get them to trigger it or is it just broken for me

Maybe I am just bad at games but how do you possibly finish level 1 without using your gun. I have tried a couple different ways with no luck!
