hey i really liked that, i think its something new and i would really like to play some full version if it´ll exist some day. that´s why you got 5 stars from me.
just one thing i want to point out: i accidentally clicked at the beginning so i couldn´t read the hole description, so i didn´t know that there was the possibility to leave some marks and only read it in the comments here, but i could do it anyways and had fun. on the other hand that´s cool for level 1 to 4. i
just wanted you to know that it may be a good idea to split the description in two levels.
hope i could help and that you move one with developing this game
