So, you may not care for to put the effort in, but if you select “new game > Overwrite Save File” at the start menu, you can reset the bit of the game that gets soft-locked around the bombs/Low Exit fight. The game does get more interesting after that, IMO, and I understand if you can’t be bothered.
I will be investigating a save file hack to fix it, but that will involve mucking in indexedDB, and running JS, which might also be too much effort, heh.
If you got softlocked somewhere else, I’d love to know
