I loved the game. Like a lot!
It was my first time playing on this version of the game and I am happy that it was.
However, my biggest gripe with this pre-alpha is that the "end" achievement should appear earlier. Some late story based events could have closed this one off, but instead I felt dragged over uneventful days before getting the achievement.
Other thing is physics bugging out so much making us loose certain items, or have them become unusable. Those are necessary to fix.
Thirdly, and this is a bit nitpicky, the nature of some moonlogics of the game make exploring its secrets not that fun. The internet will always provide the necessary steps to explore the game 100%, but would be nice for many mysterious activatable elements to be 1st, worth it. And 2nd, be interacted with in more than 1 way. The game is pretty much an Immersive Sim, and would like to see you incorporate the mindset of an Immersive Sim game to some of these secrets and elements. It would make more players find more ways and discover more things in the game world without the use of the internet. An example is the locked Bunker. If that card gets shoved out of view, you hardcoded a solution where it teleports on top. Not good at all and is really a bad solution. Make it possible to enter the bunker in more ways.
