Pro tip: turn off WiFi while playing

This game is just puzzling enough after a certain point, but then it just repeats levels. I’m at Level 1048 and I had that feeling of “I’m sure I passed that tree 5 times now”. However, it makes up for lack of puzzles with a building mini-game.

Why did it take me so long? Because the puzzles are very addicting w/o ads. I kept going into a trance as I was solving them. The puzzles are easy enough, but very satisfying to solve, and the UI is pretty good.

Some things need to be fixed.

This is a good game, but there are some things that desperately need to change.

The first thing that needs to change is the difficulty of the levels. I downloaded the game less than 24 hours ago and I’m already past level 100. And level 100 wasn’t even a challenge. It was just one stack of blocks that could only go one way. Next thing is the fact that you earn coins every five levels. Since the levels aren’t even that hard it is like you don’t even need to work hard or strain your brain to earn the coins. It is like they are giving you coins for no reason. Another thing is that the app drains your phone’s battery. When I first played the game I played for about a half hour and my phone drop about 30%. I can be on safari for about an hour and only have my phone drop 10%. The final thing is that there are too many ads. After every one to two levels there is an ad. For every three redos you have an ad. I get that the company is making money through the ads but if they put to many ads it will make people not want to play the game because they have to deal with multiple ads which really downgrades the playing experience.

Please fix these problems because if you do it will make the game way better and will make more people want to continue to play the game.

It’s ok, but not great....

We were curious what these “POPORE” developers were about, so we decided to test one of their games.

Firstly, the ads! There’s an ad after every 2 levels. I tried turning airplane mode on, the ads still popped up. Heck, I even unabled the Wi-Fi, but the ads were still playing. This is annoying to say the least. Either add optional in-app purchases or not worry about the income whatsoever. This truly needs fixing.

Secondly, just outright laziness. I get it, these developers put quantity over quality, but this level of cheapskates and laziness is unacceptable and overall a horrible tactic for game development. Every single game by Popcore is just copy + paste. It’s ok to put quantity over quality sometimes, but at least put some effort and creativity into it.

However, we did love the variety of customization. Not only can you change the background pattern, but you can choose what you want the blocks to look like. There’s also an option to make your own buildings, and eventually a town, but that option is pointless and only to rack up ratings.

If you love boring, easy, cheaply made puzzle games, then this is definitely for you, but if you’re looking for professional gameplay, then I certainly would not advise you to waste your time downloading this.
