Thank you for playing our game! Unfortunate that you seem to have run into some bug on the playthrough though, we will work on fixing those in the near future!
Glad that you enjoyed it!
I believe what happened there was an odd bug where the game thought you drowned.
There is still about 25-30 minutes of gameplay after the spot where that happened. If you'd like, you can go back and continue and finish the game from an automatically created savefile.
Thanks for the input on this!
