I will admit the physics of the Flash game are better suited for the gameplay style. I chose to go for keeping the standard Mario physics and playtesting extensively, but my options still ended up more limited as a result.
If I'm correctly informed, Mechdragon struggled with the level a bit less than iguzamini did, what that means is up to interpretation, heck if I know what it means.
I plan to put up a video of it myself, clearing it with most likely relatively few deaths due to being as unblind as a run can be, and no recording hitches, and I'll put up a non-LCJ-formatted download link with the double jump bug fixed in the video's description. This might happen tonight (US central). Willhart, you may have already gotten a link from Mechdragon, if not you can get in touch and I can for sure get you a copy today for you to make your own firsthand judgments (should you so desire).
