Kaptain Brawe is a 2D point-and-click adventure game in a "space" setting. You're mostly on different planets that are very much like Earth so it doesn't really feel like you're in space.
The game has 2 difficulty modes: adventure and casual. In casual mode you can get hints if you need them and in adventure mode you can't. That's pretty much the only difference between them. As for the controls, you have just 2 options to choose from: look at something and use/pick up something.
The game doesn't have voice acting so you have to read the subtitles to find out what's going on. I didn't find the story to be that great so I just skimmed through the conversations. The lack of voice acting is probably a good thing, because the quite likely bad voice acting would have made the game worse for me. The music was pretty good though.
Most of the puzzles were pretty simple and easy to figure out. There were a few puzzles where you had to interact with objects that were somewhat hidden in the environment and it took me a while to find them. However, there is a button that shows all the objects on the screen that you can interact with, but I didn't use it. Once I found the "hidden" thing I needed to interact with, rest of the puzzle was very easy to figure out.
Overall it's a pretty good game. Quite short though as it only took me a bit over 2 hours to complete.
