Cute graphics. I love that you were able to pull off cylindrical spiky trap in such low-res.
Good job on you for having checkpoints, and keeping the first few segments relatively easy.
As for improvements, I think the last part (or it was the last part… the one that ends downwards) had a very sudden jump in difficulty compared to the others, and no checkpoints for a very long while. I guess it makes sense with a final challenge, but I felt really frustrated by finally getting past what to me was very difficult obstacles only to be set back by the next difficult bit. It would probably make sense to introduce low-jumping in a part where it’s quick to try again before adding it to a really long segment. I mean the traps and level was ok, I just think it would’ve been nice with one or two extra checkpoints.
Otherwise great job :) I’m really curious how it ends… perhaps I’ll watch the video below of someone not so horrible at it :P
