This is an incrementakl game. In such games, there is a "prestige" function, something that restarts the game and gives some kind of bonus, when things start to get slow, you are supposed to unlock it or get to it and restart to get that bonus. I played for a while, it has not unlocked yet, perhaps it will soon. I will play for another hour or so and see.
Yeah, this is the first incremental game we've made, and we only gave ourselves a week to do so, so we didn't have enough time to implement prestige or any number of other features that are standard in an incremental game. We do have plans to revisit incremental games in the future, using everything we've learned from this game and giving ourselves a little more time to make a more feature-complete and interesting game in the genre.
Thank you very much for trying out our game and for leaving us a comment!
The game should save your progress automatically, but it's possible to reset your progress from the Options Menu.
As for the deadline, we're experimenting with a development system that forces us to finish games quickly. Once we've applied it for a while we'll do a devlog/blog post about the specifics and how it went.
