In Zombo Kombo, you play as Jeffrey, who has somehow stumbled into this frightening forest. He follows your mouse cursor and you must fire bullets at the fantastical creatures to attack them. To fire bullets, click/tap the screen and the bullets will fire to where you tapped. Medkits and swords may sometimes appear. Swords send a fury of bullets in the direction you're pointing and medkits heal you.
I made the pixel art myself, and the background can be found at: deviantart.com/such-a-dreamer/art/Campfire-in-the-Forest-143833722 Suggest things in comments!
