I keep meaning to make more kaizo levels, but haven't. Here is a single kaizo level. Give it a play; although, it's probably best to not play it and instead maybe give it to an enemy.
It's been awhile since I checked this out, so not sure what will happen if you beat the level, it may just take you back to the start screen, so please don't be disappointed it is still quite an accomplishment to have beaten it!
If you have any ideas on how to make this level more difficult or more unfair--post a reply!
