I really enjoyed this game! I saw the video you made on it a few months ago and finally decided to Play/make a video on it!
I played through the browser because I couldn't get the either of the downloads to work sadly.
I had No issues playing it until levels 8-9 It started lagging very badly and every time I would repair something it would make the lagging worse.
Eventually the game froze and wouldn't work towards me finishing up level 9 so I never got to level 10 but I assume it would've been the same issues on that level as well.
Kind of sad I never got to see an ending or finish the game but I still loved playing it overall and will come back when its working!
