I have to admit this should have been 4 stars "game-wise" - I'm giving it 5 because I've followed the development for a while now and the developer keeps his promises and listens to the community.
The game is also great. At least I like it a lot. Don't get me wrong - there are a LOT of things to improve... specially the fucking which is just boring at the moment because of the space mechanic. That being said, the quests are just fun and great, the story is nice, puzzles are fun, the game looks AMAZING and overall, I had a lot of fun.
Most importantly however, as I mentioned, the game keeps improving. The last build is much better with performance, there are always more and more things to do, new skills with each build and the developer always actually keeps the promises. Sure, they are late once in a while, but honestly - how many developers like that are there? Follow their game from v0.1 to no and you will be very impressed, I think. I think we should support people like that and so... easy 5 stars from me!
