Another bug horizontally connected walls only half blow up the top half stays but is not a physical object and the shop button on the next level screen seems to be broken but only on level 8
Enemy bullets just either stop or float sideways when hitting another enemy
Not as important but the double in double barrel and double shot is missing a u
Also if you really hug a corner with double barrel you can shoot without geting shot
Also I don't know if it is just level 18 or all levels designed with the same layout you can go through the wall in certain places
Next button on 18 isn't working
Level 19 can't be clicked on (is 18 the last level so far or is it just unlucky that both ways of getting there are broken)
