By far the best traditional roguelike I ever played and I highly recommend you to check the devblog, because my words, even if I go into details, can't describe how complex and easy to learn the game is and I mean it in the best possible way.
Basically you build yourself by taking parts from enemies or finding them randomly and if you don't agree with my subjective point of view about how good the game is, try it to check how the progression system works at least and after that you can decide for yourself if it's worth to keep playing it or not.

(if you have problems with vision, consider that you will be dealing with a lot of information in a small format in terms of interface and gameplay, the developer has explained in detail on his website why you can't enlarge anything other than the font in the options)

Edit: I forgot to mention, I played it without any problems on a laptop with a 15.6" inch screen and Full HD resolution, but for example it could be played better on a 27" inch monitor with Full HD resolution, because the more pixelated the image, the better the game will look for obvious reasons.
