Seems like you tried to play it on your phone, which it looks like works on android. Android doesn't really allow for web browsers to access pages that are stored in local storage and consist of multiple files. In other words, files might be there, but your browser has no idea that they are.

Just noticed that the way out of the playable area no longer works, is it on purpose? Is there a way to reverse from the blue dragon pool toy thing? Every time I try to use the blue med kit, it just pops the main character. Is there a way to repair them after the fact and, by chance, inflate them back even? Going to other pool toy inflation rooms doesn't seem to help here, too. And, lastly, what's up with the yellow med kit? Should I use it before the transformation? Because, it seems to not be usable after the transformation concludes. Also found out that the width of corridors differs from place to place: there are places more accessible and fitting for a giant inflatable pool toy and, unfortunately, there are the less accessible and fitting ones.
Also just had a look at the credits for the first time, and it looks kinda hilarious with it being A-HIDEO-KOJIMA-GAME-esque. XD
I tried to run AfterShift again today, after fiddling with it and proton for the considerable part of yesterday and in the end giving up for the day, and it just works now (every version of the game, except for 0.6.1.x since I don't have them). That's for not knowing what's up with working, breaking and working again all of the sudden, I'm here with you for it.
Thank you for offering to temporarily open downloads for old versions, but, as stated earlier, everything works for me just fine again now. I wouldn't mind getting to have 0.6.1.x versions at hand though. 👀
Regarding windows in a VM, I'd like to not. I'm a lazy ass, it's too much hassle for me to set it up and then spin it up every time I want to play a game and then turn it off just so it doesn't gobble all of my ram and hangs the whole system. :-P
It is located in the Lizard Cove. In order to access it, you should go to the bottom of the map where there are three lizzies guard three eggs and a pile of gold bars. There's also a pond there. You should enter to underneath it through the neighboring wall sprite to its left. Then you just follow the walls to the level's right and soon enough you will encounter the stalagmite, go to its right and there will be a strange looking pile of gold. Just collect it.
