I'm going to compare this to Minecraft because most people looking at it probably assume it's like Minecraft. But the thing is, it's not like Minecraft at all. The main focus of Minecraft is survival, but Blockscape is focused more on building and exploration. The possibilities are endless as far as structures and their details are concerned. You can tell that by just watching the trailer.
It feels like early access, there are some bugs, optimization is not great-- but with time, those will be gone.
--FEEL AND LOOK-- This game feels very nice. It looks a bit cartoonish, almost, but fantastical at the same time. The colors from the foliage blend well with the grass in each biome and the water looks crystal clear and crisp. The materials that you use for houses have a rustic feel to them. Underground, the caves are clean, and ores shine different colors according to what they are. Trees in the forests are really colorful, along with the grass. My rating for the feel and look of the game: 9/10.
--GAMEPLAY-- I have yet to spend more time messing with the game but for now I can say the gameplay is good. Not amazing, but that's understandable for an early access game. The replayability is infinite, because the structures you can build are infinite themselves. The voxels in this game are small, and they morph together to create a smooth look. In the screenshots, you can see what I'm talking about. If you scroll your mouse wheel, you can choose bigger chunks of voxels to break. Once you finish breaking them, whatever you break is added to your inventory automatically. No need for picking up any things that fall. My rating for gameplay: 8/10.
--WORLD GENERATION-- The world generation is much different than that of Minecraft, for example. In Minecraft, biomes are a lot of times hard to navigate through (with the exceptions of desert, plains, etc.). The biomes that are generated in Blockscape are mostly flat, however, they end up sloping together into high mountains and low valleys. Some of the valleys are filled with ponds and lakes. The forest biome is my favorite as of now, there is a ton of shade in the forest and it feels very immersive. You can change a seed to your liking (such as in Minecraft) and each world is COMPLETELY different. There are castles and other buildings that are randomly generated and put into the world. My wish for a future update would be for there to be less plains and more forests. World generation rating: 8/10.
--UNDERGROUND-- I feel as though everything below the ground deserves its own section in my review. The cave generation is very well done. Every cave seems to be different, there are a lot of wide open areas underground which makes the underground more dangerous than in Minecraft, since it's easy to fall off a ledge. The darkness is realistic, and there are random glowing gems in the underground that help light the way. There are also bugs that you can collect underground that you'll find while mining.
--OPTIMIZATION AND SETTINGS-- When you start the game, you get a few choices for the settings. Vsync, foliage detail, surface detail, etc. I can play this game with about 25 fps on max settings on my Lenovo Y500 laptop. If you want my specs, just google that laptop to get the specs. I do get some graphical errors every now and then in this game, the chunk loading sometimes bugs out and the voxels don't load right, leaving the world transparent. ALT+TAB breaks the game as of now. My rating for optimization and setting choices: 7.5/10.
--CRAFTING-- I haven't had much experience with crafting yet, but you do get a nice little menu with the choices you have to craft with. No need to go to a wiki to find out how to craft, either. I'll update this part later when I have more experience with it. :)
--SOUND AND MUSIC-- It is possible to turn the music off using commands in-game. There's no options menu yet. The music sounds like what you find in the trailer. The sound effects are clean, and water sounds are not blurry. The music sounds like what you find in the trailer, plus a bunch of short piano songs. Sound effects: 8/10. Music: 8/10.
I'm going to keep this review updated as I play. Feel free to ask me any questions in the comments. :P
Total rating for the game? With everything combined together, I'd set it at a solid 8 for an early access game.
