Capsized is a game with good ideas, but numerous design issues.
The game features a cosmonaut on a green planet fighting green aliens against a green backdrop and behind green vines. Yes, it is as cluttered as it sounds. The main menu, which consists of white text on a white background (which thankfully scrolls to other colours so you can actually read the text) gives you a good idea of what the rest of the game is going to be like. Eventually, you get used to it, but the developers do not seem to understand that 'good graphics' doesn't just mean nice looking textures. You have to use contrast as well. Draw the players attention to important things, don't hide it in a field of clutter.
The vsync option in the game also does nothing (at least on the Linux version, anyways), and has no frame limiting. In other words, no matter how slow or how fast your computer is, you will have loads of screen tearing. I switched to windowed mode since I have my window manager (Compiz) set to vsync windowed programs whether they like it or not. I then discovered that the game doesn't try to keep your mouse in the window, so be prepared to accidentally click outside of the game a lot.
Moving on to actual gameplay, the idea of using a grappling "hook" to swing around a low gravity environment and toss enemies around sounds great, but it behaves very strangely mechanically. Shooting a grappling hook horizontally into a wall somehow manages to let you move upwards? I also found the ability to stick to walls was preventing me from moving where I wanted to go instead of helping me.
The are some other minor issues that could have easily been fixed had more rigorous testing been done. For example, many of your weapons cause splash damage that does very high damage to you if you're too close to where it hits. There are also rapid fire weapons that fire while you hold down the mouse button. When you expend all the ammuniton in one weapon, it automatically switches you to another weapon, firing it if the mouse is currently down. See the problem?
Oh, and the game freezes when you try to exit it, so there's that too.
