It is very hard, but what a good game! Juicy and addictive, it also perfectly matches the theme. Good job!
I could not reach +30 score for the achievement :'(
Here are remarks about game design (my very personal opinion, of course) to make the gameplay smoother: I would have appreciated some more health in order not to die at first hit. I sometimes get stuck because of obstacles that have a (non-intuitively) big hitbox? The weapon are quite hard to pick up (maybe allow to pick them from a greater distance?). --- I think that solving only one these issues could be enough to make the much greater game than what it actually is.
