nice one!

Very cool. I see a lot of potential. Nicely executed skip. We can shave off a lot more time of this game. Keep going!

I managed to somehow successfully and usefully phase through a block.

Pacifist is possible (although not very consistent)

thanks for that info BlastMagic, it finally makes sense. My theory is the following: since picking up coins changes your "speed" the math doesn't work out for the hammer anymore allowing you to massively change the vector of your acceleration. I will be looking into it further ^^

Just having coins or collecting coins while using the star powerup?

I have no clue what actually happened here but it looks like I gained so much speed with the star upgrade that even the camera broke. If we find a consistent setup for it we could basically "warp" to the flagpole using the last star upgrade (In this case sub 1:10 would be possible).

Moreover it also looks like with enough speed Mario is able to teleport through blocks (presumably the collision checks won't apply) so if there is any chance to get something consistent out of it it wouldn't be all too crazy that we could "warp" using the first star to reach the flagpole. (In that case sub 40 seconds would be possible)

very interesting actually

I love the jump over the first big gap. Very clean. Overall your first part before the first mega mushroom is very impressive. Also how you dodged the last mega mushroom was cool :)

I repeatedly encounter some glitches/bugs while playing:

1. "Acceleration": Out of seemingly nowhere Mario accelerates IN his movement direction (but in the OPPOSITE direction of his hammer)

2. "Invisible Blocks": Out of seemingly nowhere Mario accelerates in the OPPOSITE direction of his original movement and in the OPPOSITE direction of his hammer. (I am pretty sure it's the same as number 1. However since I don't understand it I decided to list it extra)

3. "Getting Stuck In Blocks": if you have enough speed and hit a Block in the right place Mario gets Stuck in that Block. (I was unable to get him unstuck but I don't know whether it is possible at all.)

All of this glitches occurred to me without any upgrades/items but using the star / mega mushroom makes it way more likely and I feel like you can get them somewhat consistently using them in certain places. I think in the future we could use them to use faster routes. (I get glitch number 1 the most with the first star before the big gap).

I write this post to ask two questions to the rest of you:

1. (I use the Linux version of the game) Do these bugs also occur on the other versions / to other people?

2. Does anybody understand these glitches better than me and has ideas / actual setup ideas to use them?

If my description is to vague or whatever I've uploaded examples of these glitches with the same names on my YT. (Not an advertisement lol)

I'm am pretty sure that both categories are technically possible. However, the controls are so imprecise that I can't imagine that these are realistic categories. You would have to burn and grind through so so many runs just to finish one of these categories even once.

For "Coinless": For me the penultimate screen is the deal breaker. If you take the top route you simply will hit the coin block. (I haven't seen a single run in which this doesn't happen). And if you try to jump over the bottom gap you'd have to stay over the coin arch (as you can't go through it) while not hitting any blocks above you. This would be so precise that it would kill almost every single run getting so far. That's just endlessly frustrating. (And I also haven't seen anybody achieve this precise jump).

For "Pacifist": This one is much more plausible to being run. However the second vertical climbing section before the penultimate screen breaks it here for me. You die so easily in this game. I seriously doubt that you can consistently get over that Goomba while not killing it and you not getting killed by it. (Again, I haven't seen a run in which this is achieved at all)

My suggestion would be to give the runners a little wiggle room. This would be achieved by the category not being called "coinless" but "low coin%" in which you can collect like 2 coins at max. Collecting less would obviously be still alright but it would make this category much more consistent and fun to run imo.

On the other hand if "pacifist" allows you to kill a single Goomba we would achieve the same benefits for this category.

If there are any strats to avoid my concerns in these categories I would gladly learn them and delete this post :P
