I love the artstyle and art direction. I think the medieval-like direction is really well done, with the colour palette and lineart. The chromatic abberation is not distracting, however a setting for it would've been cool. The game is very minimal when it comes to text, and the upgrade cards are done well enough to understand them just fine. It's reminding me  a lot of a children's comic of some rock dudes going to space, but I cannot for the life of me remember the name of it.

The game is short and simple( the main game takes around 18-20 minutes), can get quite challenging. I really like the fact that there's atleast two ways to repair the castle, one being a challenge.

All in all, good, short, simple, artsy. Just settings are missing, for volume and such, but it did not interrupt the gameplay of it.
