i have no more upgrades left and finished the game, how to get this achievement?

Couple of game breaking bugs so I refunded for now as I dont have the patience to start over. If you click the Gem Eater (locked) it uses up your diamonds and you cant get them back. Second bug, is I cant see the prestige option anywhere. If it wasnt for the bugs it would have been a good game to play through....

the ability to skip the START and Item used screen for quicker restarts. its just a second but it adds up when you restart the level over and over again. Or maybe a toggle option to disable it? great game so far nontheless!

It says flying off into space starts a new journey, but I don't see any sort of 'new game+' or.. .super prestige, or... anything indicating that there is additional content, or replayability other than that messaging. Is there additional game play after flying off into space? Or is the wording just weird? Thanks for the fun game!...

I quite enjoyed the demo, played through a couple prestiges and this has a lot of potential. I do think the repetitive recollection of badges is going to get old, fast, I was already fed up with it after the second time. I get that its a prestige reset, but there's a lot of "manual" grind each time to get everything uncovered which I could see myself losing interest in quickly. Perhaps something unlocks later that alleviates this? I played until it told me I'd reached the end of the demo, then figure...
