Not responding to any input of the game ui at game main screen

You can't close out of the window advertising the next game, you HAVE to select to wishlist it, then you can exit the steam overlay. But when you try to play the game it brings up a window to buy upgrades you can't afford then you have to hit X and the entire UI freezes....

So I'm level 6 and I can only go up to Wave 14, is there a way to do an endless mode? I'm sick of having to end and restart a good run because I reached the max wave.

Really want to say to developer that keep the good work, is really a nice idea and love to play it. Now some feedback, no info on terrains, what they do and how. There will be diferent part of maps, different biomes, maybe some random builds with effect to discorver (landmarks)? Keep the good work....

Having an issue where occasionally a wave of attackers doesn't complete. This has happened when enemies get stuck on their spawn point and no damage source can reach them, but has also happened when no enemies remain on the map. I've only encountered it i later waves. Toggling through speed and menus does does not jog the progress free. Only option is to return to main menu, losing progress. Anyone have a solution for this?...
