Well for getting all achievements you must achieve score of 150 points.
The easiest way is to just complete level 1 repeatedly for doing that just when you complete it click on "←" when is score shown and just repeat that progress until you get a score of 150 points.
P.S. It's done in 5-10 minutes

Thanks for reading this fast and simple guide; Personally I didn't think you can repeat all over level 1 and still saving all points, so I decide to do simple guide about it cause there is no guide for it. Hopefully, this simple guide helped you; If it did, I would appreciate it if you could leave a like.
