I feel like it is "ok" for a game to ask to pay. However, this game just asks for way to much. The cooldown one is the only one i understand. You should not make people pay to be able to play your game or for making items. (in a game it could actually screw you over if you cannot make item or buy the material for the items.) The more time you spend on a game the more likely you will be willing to pay for stuff. Paying for things should only be used for enhancing the game and not for screwing over players who can't pay or just plan "don't want to" or don't think it is worth it"
There are many games in which you have to pay for thing but people do little complaining about it because they are getting screwed over when they play. It is alright if people who pay can do everything faster then other players. It is not alright if non paying players will never be able to reach the level of paying players, even with more time and skill.
I have tired 3 times and received different glitches each time. One time the game froze. Another i could not make money and another have of my building glitched out. I feel it happens randomly and you are lucky if it doesn't because it happened once in the beginning and once when i had many people.
This game is alright. I find it isnt the best because the items stay the same and are hidden by size. Like lets she how hard it is to find it because it is sooo small you can't tell what it is until you click on it. Some thing were hidden creatively but really it was kinda annoying and not fun.
The issues is that it just takes to much time to draw the unit them send them where you want them to go and not randomly. It makes t too hard to be very fun. I mean it has a lot of potential but maybe change the shapes. Circle has to be connected which made it very annoying and actually harder then the other shapes. and the units might be better to send automatically. Like in a straight line to the one across from it. As well as make the enemy unit do it as well. It would really balance the game out because i was annoyed when i sent a unit out for another but they were sent out at and angle and i didnt hit them. It was very annoying.
I have to agree with the other comments that this game is very easy. I found it harder to get the pieces to click into place than solve the actual puzzle. It is a fun but over used idea. It would be a ton better if there were more and harder levels.
What makes them game hard and probably a little unfair is the slight changes in hue. I do not find this an issue for myself because i can tell the slight differences but some people cannot and seem a little unfair to them because even i find it hard.
