Too many ads.
This game is very good overall. I understand that ads will support the developers because of their hard work. However the amount of ads in this game is insane. 2 mode in this game which are level mode and survival mode. For every level it will require you to watch an 10s ads. Each level will take around 1 mins of playing this game. For survival mode, every time you level up there will be an ad pops up, usually take you also 1-2 mins for 10s. I play this game for 15 mins and i am required to watch around 10 ads. Wtf man, if it was half of that ads I would be fine but this is too much even though it a good game. Seriously, if you downplay players experience like this then it will not last long.
