Just ads

This isn’t really a game. It’s just a mechanism for ads for other games. Ads are ridiculously long you spend more time waiting for them to be over than actually playing the game.

Очень много рекламы!

Очень много рекламы!!!! Желания играть все меньше и меньше!!

Hilarious greed.

I appreciate that you need to make money but I won't be screwed into watching 100+ second advertisements.

Rubbish

Does not look like the gameplay advertised, and very quickly becomes swamped in ads and impossible to complete without watching even more ads. Don’t bother!

Downloaded from watching an ad, thinking yes a wood screw intricate game, a challenge, yes!
NO ITS NOTHING LIKE THE AD. NOW DELETING
