Finally it is out! Arrow Keys to move. H to change weapon. Space to use weapon. Walk up to merchants to have them sell you stuff. As the game goes on it gets increasingly harder. Money Hat Guy gives you ammo. Doctor (obviously) heals you. Wide Eye Guy upgrades you speed. Press P to pause (kind of buggy) Killing enemies gives you money. Over time enemies get faster. Say "yes" to buy, "ok" does not work.
Thanks to supawigibwos for inspiration. All sprites by me. If you want to use them ask me and give credit. 1.1:fixed bugs
