Genuinely awesome game, not only in the sound and art feeling super unique but also being really really fun to play. I found myself often replaying levels and really thinking hard about the solution - and they always felt satisfying when I solved them. The variety of levels and tasks was also really good - some of the ideas especially with the last level were great.
If you were to improve upon this, the sinkhole level consistently gave me the win even though all the houses fell offscreen (although i have no idea how I'd solve that one legit)
My main issue is that half the levels were not very clear on what the danger was from the level name alone. Having more indication of what the threat is beforehand would be nice.
Lastly, it'd be nice to get more use out of the digging mechanic and maybe even mix it with the building mechanics.
Otherwise, you did flawlessly and I'm happy for you about how popular this game got!
