so far I've been enjoying this game however I cant seem to progress any further, I even paid for ad free, I completed the levels 15, I got all the research cards maxed out, but that's it? there's a menu yet to unlock, but as it won't go any further im unable to unlock it.....any help would be nice, i dont want to feel like I just wasted money on this..so it's one star unless you fix this...

This is one of hard core idle tower defense games I'm looking for. It would seem a little slow and easy at the beginning but the challenging on the later stages took me a lot of tries. Hope to beat the final boss as soon as possible. Waiting for the new maps and modes. Keep up the good work!
