Great little game. It reminds me a lot of Minicraft, (the 2D Minecraft styled game Notch made during a game jam in 2011). It's a simple little top down game where you try to survive as long as you can.
It's quick to pick up and play in contrast to Minecraft and other games like it that require a larger time investment. It feels reminiscent of a retro arcade game, the only goal is to survive as long as you can. Your "score" is your total survival time. It might evolve from this as time goes on but for now if you want a simple, pick up and play experience in a randomly generated world ala Minecraft, you'll enjoy this game.
It even comes with mod tools out of the box to make your own mods. I made my own custom player sprite in a matter of minutes with the mod tools bundled with the game, but you can tweak just about every aspect of the game with them. These tools are a great addition and definitely add a lot replayability to the game.
The game also runs great on low end PCs. I have a really low end machine, an HP Stream 14, and it runs on it without any performance issues at all. I've also experienced no crashes or bugs yet, even in this early build of the game. I'd recommend this to anyone looking for a survival sandbox game without the huge time investment. It makes a great alternative to any games like it you currently play due to the pick up and play nature.
