Rydmkapsel is like an isometric Tetris where you have to lay down blocks. But the twist here is that these blocks are populated by... well, I'm not sure what they are, but they look like rectangles. Each block has a function, so you have a block for defense, for harvesting, for gardens, for cooking and a few more. You have to combine all of these blocks together to create a living world where the main goal is to explore and survive. You can't build a straight road unless you're lucky because each time you construct something a random shape is generated so you have to work with what you get.
At the bottom of the screen you'll see a bar filling up. Once it's full enemies will attack. It starts with 2 enemies that can easily be defeated, but once the wave is over, the bar will refill and new enemies will arrive. The longer you survive the faster the bar fills up and the more enemies will appear. It can get very hectic, especially if your workers can't get to their battle station in time or if you have too few people left to defend it all.
And that's where the exploration part kicks in. There are monoliths to be discovered that can positively alter stuff. Like, for example, making your workers move faster. These seem essential the further you get and it's recommended that you discover and analyze them as soon as possible. There are also multiple objectives to complete, but at the moment for me it's not entirely clear why they're exactly there. Maybe to give you a goal, I don't know.
Graphically the game has a very minimalistic look. There are no bells and whistles, just the essential stuff. The music is also very soothing... until you get that battle alert at least.
So nothing fancy here but it does look sharp and colorful and has a style of its own which I can absolutely appreciate.
The game also feels very relaxing... until, well, things are about to fall apart. Just like how the real Tetris feels.
Anyway, I like Rymdkapsel. I like it a lot. You should too.
