Pretty fun game, didn't hold my interest too long. I found the level designs of 5 & 6 to be tedious as opposed to fun. I think if you make certain areas so precise, it takes away from the fun. Level 6 is a good example. Just getting the right bounces to get under the first few blocks is just tedious and require going slower. I think the level design would still be challenging if it wasn't such a tight fit. I found it to be more tedious than fun as levels went on. So I stopped. Alot of tight fitting areas is really the cause of the tedium.
