This is sick dude. Such a fresh take on the Survivors genre. Really nice retro art, a great simple gameplay loop, some really meaningful upgrades. Incredible work for just 72 hours. My only critique is I would maybe suggest stealing from Into The Breach and showing the enemy movement tiles so it's a little easier to plan. The yellow guys particularly can jump quite far and can catch you by surprise. Otherwise, this is could easily become a full game. Nice work!
