great idea for a game was a lot of fun to play and even a character selection screen :P I am still a bit confused what the seaweed does and not sure how much health i seem to have all the time. Playing around with the gun feels fun in general was nice to play! This this game would play better full screen or have it capture the mouse so it does not leave the screen. and an online hi-score would be amazing to add, no sure what program you used but think brackeys even did a video of a simple hi-score system/ website a while back not sure. but was not really hard to do at leased not this simple one. or at leased have a hi-score window for yourself.
Overall a fun little game :D Don't really know what kind of other feedback i can give really :)
