This has potential.
It's up to you to pursue the potential this game has. Like first make it so it doesn't have that "1 monster left" bug after level 5, and make it so clicking shoots, and the arrows go faster, and overall make it a more intense game, and it could be a very good game, but I know that's a lot of work.
game bug
It looks as if the counter is + 1 or a sprite lost its way in a few levels, good game thou, yeah add some creapy background music and a sweet background and I would play
quite dodge
nothing to new or interesting (lol). pretty boring, needed some variety and/or some background music.
glitch?
I liked the game - hated the laugh sound.
I ended up with 1 monster left but it would not enter the screen. the game just stopped -nothing to shoot at, no advancing or dieing.
change the backgorunds do something
i dunno i probably could of gotten further but it just got boring but it had potential to be a very addictive game
