First game of this kind I have seen so far. It is working fine, your controlls are easy to understand and the functions seem to work properly. You have a start and an end screen very nice!,
I don't like your artstyle, but that is just me :)
But:
- I am missing a healthbar!
- I did not know at the start, which one was my character,
- Please add some dmg idicators, so that you can see that you hit, or that you were hit,
- let the different enemie types spawn randomly so that there is some more variation

Good game!

Nice art work! really organic feeling.

Muy buen juego!!!! Lo unico que algunos personajes no me funcionan jajajaja lo juego al canto nordico de "toma, toma, pija por el culo" AJAJA te quiero

Idea sounds interesting, instructions and sound off/on work, but I cannot start the game. Please resubmit when this bug is fixed.
