Hi there. I can see this is your first level. It's a bit of fun, and yes, as you say "easy" Just a little note, when you build stairs, leave headroom for B. So rather than a square block which makes him squeeze his head, use a wedge shaped stone block. It produces a smoother effect as he climbs stairs. Otherwise, yep, a good, fun little map requiring use of R and B to get all the stars.
Sorry, one more thought. Instead of screen shotting the build level, use the share option. I share to my email, then save the image, then that's the image I upload to the forum, because that's better than the screenshot which I found was not suitable to load into mekorama. I had to manually edit your image, cropping and zooming it, before mekorama would accept it.
Hi & welcome!! very nice first level... nice design with an interesting opening with the balls falling and the FDs ( Free Draggable) are contextualized... also I was surprised with the end cause I thought that R would stay stuck but no ... it went back a bit but kept moving forward until he reached the win ... a level of 4 stars but since it is your first level I give you an extra star to motivate you... thanks for sharing @Myselfmeko
