I enjoyed that even though I did expect a zapper or something to tick me off. The passages were hard to see but not hidden so excellent work.
Yes,you increased the difficulty a bit but I decided to keep my rating... Thanks for sharing @Md Siam Ahmed
Fun to explore, . Lots of interest along the way. I reckon it's a 4.5 star level, so I will round it up to 5 stars, .
