That's one of the first games I've ever played on this site, maybe it is even the first, coming back to it after some time is so nostalgic!
Even though its controls could be a bit better, it feels special for me!
I really like how this game on one side challenges your thinking but on the other provides really useful hints so you need not frustrate when you don't get a puzzle!
It was really an eerie experience to revisit the places from Subs 1, 2 and 9 to discover largely wrecked with resin as if hundreds of years passed between the events of part 9 and 10!
I hella liked the interatcivity and humour in this game!
BTW, creators team, are you from Mongolia (as a hidden message implies? ;) ) Or from Russia? You have a typical accent! )
I have completed the game, and my only complaints are that this game could be longer or it could have a level editor, so players could design their own levels.
