My initial thoughts / Comments:

Art and Music are cool

profile selection screen should work with both wasd keys and arrow keys

Enter is Space? Why? Shouldn't Enter be enter? - This was very annoying

Mouse Support on the profile select page? 

I didn't see an obvious way to rename the profile select page

On the HUD it is unclear what is what on the left hand side. The right size will become clearer after playing perhaps? 

Why is Escape not the option to get to the pause / status menu? 

How to scan things is unclear holding space bar while locked onto to a point of interest doesn't seem to do anything? 

I see first you need to turn the scanning on with Q then hold down space this needs to be made more apparent in the tutorial text? 

Bot moves in a super static fashion walking animations need to be added

Perhaps when switching from Brain to bot there should be some way to indicate to the user which part the are currently driving? perhaps some text that fades away after some time on the right lower hand side of the screen

How do I save progress? 

I don't see an option to view the key bindings or make changes to the key bindings in the menu

After running into the force field I was kicked back to the main menu? No continues no nothing? = sucks

Also if the bot got destroyed why did the brain? That doesn't make sense? Shouldn't those have separate health bars? 

Pressing R in the room with the boxes sometimes makes the camera clip inside the boxes

Trying to hit the button on the wall makes the Brain and robot Explode why? 

Found the molecular printer, we need more resources in order to play with this to evaluate it

The rock world was cool. I'd like to see some NPCs there to interact with possibly trade with? This area also needs boundaries

Overall the game has the what am a I supposed to do feeling? It's not a sandbox that I can tell. It seems to be an exploration FPS with Crafting and RPG elements? The lack of any kind of save system is off putting to me / annoying. Exploring the world is fun and some of the places feel like a maze (But in a good way).

Final Thoughts: I'd like to see more element blocks added so I can play around more with the crafting / molecular printer. overall I have seen a ton of progress from the last version of the game. As a note this played nicely on my windows gaming PC no issues running the game.
