I played it all the way though. I wish you had time to finish it! After the first ascension there wasn't really any upgrades but I assume that was because of the aforementioned running out of time (also please swap out the sound for the other planet outside earth, mars I think, because it can get quite annoying compared too all the other sounds in the game). If you enjoyed making it then that's what really tells you if you should keep working on it!
