ok.. needs a lot of work
I have played your other games and this is just outdated looking and hard. It was fun, but on easy it was stil way beyond my skill level. Try adjusting enemy HP and weapons damage so you do more damage on the easier difficulties and not die so much, even the insta shield did not last as long as i had hoped for. One thing i can recommend is have a shield power up pick up so the shield lasts longer and can absorb more damage.
