Ok, i have no idea, what kind of games are included in here. Maybe i would even enjoy some of them. But to be honest, i don't want to put the effort in here to find out.
The game is super slow and laggy. And i'm playing on FF, win10, i5 with 8GB ram. So, you really manage to put that to it's limits? than something is going wrong in the background.
EDIT: seems like what ever caused the lag was finished after 10 min. Are you storing data in the background? Creating save files or something like this? Generally ok and would even explain, why it occurs at the beginning.
But even without the lag, the first game, the tutorial, "lines" - it's a pure mater of luck. I ended with lots of groups of 4, only a few symbols even had 5 times the same color, but they were all spread across the board. 7 Shapes, 5 colors, only 81 squares room, you can fill the board with an average of 2 to 3 shapes per color. And i have to collect 5 and put them in a row before the board is flooded with random shapes?!? Seems like you rally like this kind of game. But on the other side this means that player has to get through this just to discover wether the other games are better or not.
Skipped the tutorial, still no idea if i'm doing something wrong or if "lines" is just a stupid game in my mind, just to find out the next 5 games are lines again ... and i can't even play the tutorial again.
