Cube Escape: Paradoks

The game is so good, the devs are also kind enough to put walkthroughs and a short film about the game. Unfortunately as usual, I can't play the chapter 2 because I have no money tho I heared that you can play it for free in Steam. The only reason I deduct 1star is because its a bit buggy, for some reason some puzzles are hard to do because it has to be specific spot to solve the puzzles. For example is the drawing several things using pencils, I had to retried several times because Im using a phone and my finger keep overpassing the line. Another example is when Im supposed to burn things that are on the paper, it points out to wrong letters and numbers even tho I burn the correct things. Even in the walkthrough on yt, they have to click the things several times.
