I enjoyed that! Funny, not only did we both make spooky games, but we both used the same theme interpretation of only being able to see for one second at a time, altho executed very differently~
Game looks nice, and even without the soundtrack on web it also sounds nice with the effects. Have to agree with the majority that having to restart the whole game was a bit harsh, but the mechanic is fun and the batteries that grant an additional flash were very welcome! Like some people have said, procedural generation would be cool, perhaps for a post-jam version if you choose to keep working on this game? c:
Nice work!
