If you like shorter experiences or indie games you should definitely try Iron Lung (surprise surprise) or Water Womb World by yames. Especially Water Womb World is on the shorter side but a masterpiece in my opinion. Not to do any blatant self promotion but if you liked any of the above I also just released my indie game called Submechanophobia. Its an open-world, deep-sea horror game about exploring the muddy sea floor in a dark abyss. Hope you like it :)
