I couldn't enter the 'stalactite cave' due to the invisible wall, and I'm not seeing anything else, the mayor hasn't come back or anything to deliver a title drop.
There's also some performance issues, especially when placing a lamp, and that in turns leads to a lot of tunneling issues, which could even cause a softlock if you're out of energy!
Lastly I think the music needs a pass through audacity to remove the high-pitched clipping, I had to mute it after a while, which is a shame as it's otherwise a pretty good track!
Otherwise it's got a pretty good gameplay loop, the art's nice, the music is generally nice, and hopefully you're able to iron out the issues!
