Interesting concept! It reminds me of a tabletop game of some kind, and I think that may have been an inspiration judging from the hexagonal tiles. The random events do pose a certain intrigue as to how they will affect the overall outcome, but a lot of the time it's hard to guess what the various stat changes affect and there doesn't seem to be too much of an overall effect on the outcomes of the more random encounters.
I'm not sure if the main mission is also randomized because I had the same one each time I played, but if it is then that's a very good idea! It would certainly help the replayability by having new concepts and stories be presented.
I also like how the game looks, with all of the images looking great. It really feels like a space adventure with all the little pointers and designs and things.
The only issue I really have with the game is the seemingly high chance to have some kind of encounter happen, although that does balance out the fact that each individual encounter doesn't have that much weight to it.
Overall, I would say it's a very good concept that looks great, and plays quite well with only a few minor issues that would only really be a problem with a longer playtime.
