I've listened to the feedback, and APEIROGON is now easier! 

I decided to change some of the mid-level texts to the explain the game in more detail, while not being too long. I also added an in-game tutorial menu, where you can check the controls and do a quick read-through on the game's features.

Now, the general game is easier, too! Monsters spawn less often, while power-ups spawn even more!

That's all, have fun!
