Wow, it was awesome to read your review and feedback. Thank you for taking the time to do that and for having the patience to beat it even with the difficulties you pointed out! :D I appreciate all the kind words about every single piece that you mentioned, it makes me feel great to know you liked and had fun with it!
I'm aware that the game is hard, currently working on a way to soften the frustration to restart all over again. Your suggestion about the gems is really great! Didn't think about it and it seems promising. I'll do some thinking/tests and will keep you updated on it.
About what you said here: "moving into a direction off-screen and not knowing a trap lies ahead" is something I particularlly worked a lot to avoid and I made sure you were able to see every trap before going to it, so that the game would be fair. That (and the the resolution of your screenshot) makes me think you played it full screen, didn't you? There is a bug that cuts a part of the screen so it'd explain why you couldn't predict the traps. I'll remove the fullscreen option until I fix it, thank you for that and I'm sorry you experienced it. Maybe give another try in windowed mode? haha :D (if that's the case).
Besides that, not knowing where the door is is part of the design I chose, so that you wouldn't be able to predict it and had to figure it out when you come close. But you are totally right, if I plan on releasing it to a more casual audience (maybe mobile?) it needs some thinking along side the timer.
Thank you again for playing it so much and fore sharing your scoreboard! It made me trully happy! \o/
I'm planning on keep working on it! Maybe some day it'll have it's full release. :D
