Haha this could totally be identified as one of those basic iOS games scattered with ads galore. I've the comments about adding a prestige mechanic and planets, looking forward to the future of this game!
Really interesting idea, I'd recommend just writing out loads of ideas and following up with the ones that really interest you. To be honest I was kind of disappointed when there wasn't anything left to do, so get to updating the game my man!
great game to spend a few hours grinding on, i feel as though there is something missing on the left side of the screen, it feels a little too blank. all in all great concept, and great ending.
very good for a first game! continue on the idea but add more menus. also allow players to see the amount of upgrades they've purchased. keep at it bro!
