I entered this into a game jam here on itch.io - check it out!
I'm on the third level... It's quite difficult... I have to ration my ammo wisely.. Especially trying to get to the final door on the level. But I've played some pretty rough games and have made some pretty tough ones myself. So, I'm gonna try to persevere!
Let you know how that goes.... But is very fun to play and really takes me back.
