I didn't think I'd be playing as a bear balancing on a ball today, but here we are!
This is difficult but, for the most part, in a very 'fair' way. Most of the time I understood where I went wrong and how I should better approach things. The one real exception is a section with a raising platform which also has a barrel trap above it. I don't know how to judge the timing on that, since it's mostly dependent on the platform's movement, and there barrels don't have any sort of lead-up before they come at you.
There's a nice progression of difficulty overall, but I somehow managed to complete the final level on my first attempt. Probably all that training from the one right before it with the platform/barrel combo! The camera can get a little bit wonky when you turn and the inclines are a challenge to navigate since most of their path isn't visible before you start down them.
The controls are... I think the best way to put it is that it controls like you're a bear balancing on a ball, so for this game they're near perfect! Bumping into a wall or tree was, perhaps, a bit trickier to recover from than I'd have liked, but I'm already asking a lot from Stanley as it is.
And, most importantly, I really like the victory dance!
