Hello NelBella,
Could you please describe the issue? What button doesn't work for you?
I think bella is talking abt any of them, because the same happened to me, i clicked on the arrow button to continue the prologue, but it didn't work, i waited a bit, clicked it again, and i t did, but when it came to the instructions, i waited a few minutes before pressing the next button again after it not working the first time, but it still didn't work, so i reloaded it but the problem is still there.
Jenny is right, it's the triangular button that advances the dialogue. I waited a little and clicked again, and the first bit of prologue advanced, but I couldn't advance after the second page. I waited a bit but it didn't work a second time, I couldn't get to an instruction page. I could still hear audio and button clicks, but the text stayed the same.
(Edit: Also, this is in the browser version, I have not tried the downloadable one.)
Unfortunately, we could not reproduce the issue :(
Probably it is caused by high quality sprites that we use in the game and some machines with integrated Video Card has lack of memory to correctly work with them through WEB version.
Could you please give a try to the downloadable version of the game?
Some people who had faced this issue told us that there were no issues when they run PC build.
