No, of course it doesn't sound negative, thanks for the feedback.
I planned to only show 2 levels just to see how player would solve them.
I have created 7 out of 16 story levels so far, with some traps and much trickier maps.
(A friend took over 17 minutes for the 7 levels, on his first try, so i think the puzzles are not too easy)
As described, i am working on a story mode and the difficulty will increase per level, involving traps, enemies and more things that i will not mention jet, cause i don't want to spoil things
By the way, the stuck on level 2 was planned too, further level will also be challenging, there are more than one way to solve a map, and there will also be many distractions in the way.
