About this game
DEATHMOON is a brutal roguelike boomer shooter set in an underground moon complex. Carve your way through layers of the moon with an arsenal of powerful weapons. Use the tight and fine-tuned movement to your advantage to get out of tough situations.. or just punch your way out of them.
Inspired heavily by The Binding of Isaac, this game relies on synergies as its main fun factor. Every new weapon you find can be enhanced with either a blessing or a curse (or both) to offer a vast amount of variety.
Found the weapon of your choice? Now it's time to squeeze out all its potential with the ridiculous number of items you find across the complex.
Your skill will be put to the test at the end of each layer. Show that you have what it takes, or die permanently.
When you manage to survive the dangers of the moon, grab yourself a rod and replenish your sanity. You will need it down there..
