Self explanatory. If you somehow didn't collect enough, just collect coins without finishing the level, hit R, repeat.

This one is for killing your first enemy using a crate.
(I have no idea why or how this is achieved more than the next achievement. I thought this might be for 10 crate kills but for me this one popped at my 1st crate kill. Any insight is appreciated.)

This one is for killing 3 enemies with crates. Doesn't matter what kind of enemies they are, any 3 kills with crates will do.

Now this is mainly the reason I made this guide, except the last one these achievements have incorrect info.

Description says 10 demons, 3 is enough.



Description says 10 carpenters, 3 is enough.



Description says 10 zombies, 3 is enough.



10 enemies killed with bombs in total.




For some reason, the last level is easiest to beat, and contains 1 of each enemies. You can just complete any missing bomb kills on last level, so don't waste your time along the way.

Just finish the game! It has 30 levels which are pretty easy overall.

So congrats on your new 100%!
