Swordless Knight

As for the spikes, I have unfairly died by the spikes in the watch tower and the 3rd-floor retractable spikes. For the former, I jumped into the spikes from underneath after clearing the blocks first. The latter, I would die even before the spikes went up.

Oh, and there are bugs with the mushrooms and spikes. I cannot replicate the bugs every time, but there are instances when you will fall through a floor level or the whole map after bouncing on any of the mushrooms.
