It’s interesting to note that some of the feedback contradicts each other wherein some users report that the difficulty of navigating the structure of the tower was just right, and others report it being very difficult. During my initial design process of the level, I had implemented diverging paths that presented differing levels in difficulty, and that may have been the reason for the reports. However, it’s still something to keep in mind that difficulty is subjective.
Other feedback I received tied in with the lighting, particularly as one ascended higher, and that’s something that can be easily remedied. I do note that some platforms can be hard to visually distinguish because of the lighting, and as a result they melt into the shade.
The checkpoint was something I noticed during construction, that it virtually served no real purpose during the second level, and the first level didn’t have many so it needed to be done in one go. Considering the completion rate, adding another checkpoint halfway through the first level can definitely help with concerns about difficulty.
An alternative method can be to move the second level and checkpoint so that there is a hole in the ground below, cementing the need for a checkpoint, but would also increase the tension.
