After beating all levels without dying. I can say that level 76 is hardest by far. Great game, I love all those pixel retro platformer games. And also music is brilliant. 5/5

I made a picture to show my strategy. Remember that if you are playing 101 mode you will have to build spike pit traps, they damage a pirate for 50% of their current hp. Without them it would be impossible to win this mode.
I did both hard challenges and didn't get a badge ( yes I had green dot ) :/
Game is very easy. For 175k points create single long corridor with left and right swing to create double combo and get a lot of money. Between triggers place bee hives and later upgrade it to coal.
To get artifact 19 you have to get all the 100 kill achievements with all the other weapons. Then you have to DIE (important) and start a new level, and it will be in a third weapon slot. You won't be able to throw it away, and you can't pick up ammo for it, it just recharges.
