Perilous Journey

Welcome to the forum @Zhask! This is quite the level for a new creator. Well done! The solution was not too obvious and even included a few potential ways to finish the final step, which normally I would say should be avoided as it presents everyone with a different experience and thus makes it hard to rate the level. The reason that I am not saying it this time is because there are quite a few instabilities in the level and thus having options at the end to overcome them ended up welcome.

Spoiler: Instabilities

The most frustrating instability for me was not having the second ball run to the end and stay close to the rail. It is possible to get B to change the far pillar-head R's (let's call him P) path so that he crosses regardless of where the ball is, but I don't think that you intended us to play like that. It appeared that you wanted us to send B to the back and have him ride on P over the ball and to the win. The problem I found with that is that even if the ball ended up in the right space, it often caused P to lose some balance and B would either fall off or step off onto the half pillar. Thus I skipped that part and just waited for both the P's to come to the middle and then I stacked them with B on top. This too proved to be unstable at times and I had to repeat the process. The one other instability that proved the most frustrating was flinging B over the water. Using only a single height block to push him with caused him to sometimes climb up on to the block - best to use two blocks or a lever like a golf club. Even if I was able to fling B, having him land somewhere useful was the worst. Often he would just fly out off the level and sometimes he'd fall in the middle water from where he could not get out. Finally, bot stacking is also prone to obvious instabilities. If it wasn't for that, I would have won without moving B at all.

Anyway, despite the many instabilities, I did complete the level and the checkmark feels good. You obviously put a lot of thought into the level both in terms of gameplay and so many important pieces in such a small space. This is very hard to do. Hopefully with time the quality of the design in terms of consistent play will also come. You'll just have to spend much more time on testing your design - a true measure between an average level and a very high quality one. I'll let you get a bonus star today as this is your first level and it shows a lot of promise. Thank you for sharing and I look forward to more!
