I have rewritten the whole button interaction from scratch and it now works 100% in the tests. I uploaded the corrected version. You may want to empty browser cache if you play again.
Thanks for catching this :)
Thanks for rewriting that, it works fine now! I'm running into a new problem later, on Day 4 after fixing the Mazovia oxygen generators, I need to open Mazovia's solar panels, but just after I cross the line into Mazovia, the camera moves and gets stuck in the previous room. Has that ever happened in testing? I tried entering Mazovia through the bottom/middle/top of the hallway but I still got stuck. 
Oh man, that was… Kinda like Mazovia depressurisez. I was optimizing the backgrounds for scenes and had to refurbish all the triggers, but Mazovia has like 4 separate scenes on the level and one was left behind. I have just tested and uploaded the repaired version and it should work properly.
I think should add you as a beta tester to the credits :D

Oh I see, that makes sense about the triggers. It worked for me today, so no hamsters were accidentally depressurized! I made it all the way to Day 6, but as I'm walking to turn on the radio beacon and leave the hub to enter Mazovia or Panonia (I tried both) it changes from your white clothes back to the EVA suit. I get the feeling it has taken me to Day 5 again because I can go outside and check on the antenna, but I'm not sure because when I come back in afterward I can't activate the radio panel like I did at the end of the real Day 5.
I'm just having fun playing! It's fun to see where the story goes, and if I do get stuck, it's not bad starting from a save point or even the beginning since catching up doesn't take that long.
Well, that one was confusing - first of all entering Panonia would swap player icon into EVA suit, which was a dirty leftover. Second - leaving Panonia would throw the player back to EVA day actually. I missed it, as I didn’t enter Panonia during the test phase.
It is all repaired now. A single advice from the creator, finding hamster before Day 06 plays much more naturally. In fact, it’s best to search for it as soon as the main modules are powered ;)
A working version is uploaded. Thanks again for the input!
