So far the game ia really fun, but there is a bug i have found. When you complete a chapter you can watch an Ad (or skip the ad if you purchased the ad free version) for 1.5x gold. However it doesnt give 1.5x and often times doesn't even give the ammount of gold it is supposed to. I have screenshots and it seems it always give less than even the intended value. Hopefully they fix this problem as its quite abit of gold we are missing out on. Specially when you watch the ad and get less.

Edit; Ads work maybe 15% of the time, which is INCREDIBLY frustrating as ads are 99% of how you can progress at a reasonable rate. I've been stuck at the same area for close to 3 months now because ads stopped working and progression is so slow without the boosts. Honestly love this game. While there 'isn't much to do', this type of phone game has a charm a lot have lost. I hope while the game continues to grow and change, it doesn't lose that simplicity.

Game becomes boring soon. Latest upgrade adds artifact you cannot use gem for chests, you have to spend real money for it. It says TD but there is little about TD. Many upgrade options but you dont have too many choices. The resouces needed for mid/late game upgrade is insane, you need to grind the levels again and again. But the game play is so boring and using a script to grind it for you is hard because they add some "rewards" sometimes after the level to prevent you from automating it.
