Oh man this is positively insane! The original Tomb Raider games are probably my all time favorite video games. I recently revisited Tomb Raider for PlayStation in an emulator on my laptop. I find it a bit mind-blowing that OpenLara in the browser seems to be performing better than the native PSX emulator did.
I think perhaps the ctrl-action button is more sensitive here than it was in the original PC version? In order to get out of the water hole I had to swim into the corner basically. It was a long while since I played the original on PC though so who knows.
Mad respect.
