Hey, this is a great effort. I didn't really understand how to use the wave signal machine, but I really enjoyed the little world you built and walking around it.
It's a shame not many people are rating this game, so I want to leave a meta comment/feedback. For Ludum Dare, you should go and rate as many games as you can. Then others will see your game more and try it out. Actually, it's really a good way to get people to try your game, since most jams people won't even be incentivized to play your game. But you also have to go play (and rate) others games, and probably a good idea to leave a comment with relevant feedback. Basically go to https://ldjam.com/games and try to rate 20-30 games before the jam is over in 17.25 days
I see you all have done LD before and got ratings on your games, so maybe what I'm saying is uncalled for and you know how the system works and possibly haven't had time to go rate games. But in case you didn't I felt I should let you know. Anyways, good job on this game!
