Thanks for the constructive feedback, that's really cool! Yeah, all in all, we agree with what you're saying. Some of the issues pointed out were on our todo-list, but we fell short on time... The others though are quite obvious now that you say it. We probably won't update the game in the futur, but it's definitely something that we'll take into account for our next games. We definitely should reward a little bit more the player for finding secrets!
Indeed the game is quite linear and could benefit from more reactions to what the player does!
Thanks a lot again for such a detailled comment, it's amazing that you put the time to give so much feedback!
