I first made it into CO on the daily on Jan 2, 2021, dying in 7-7. A month later, I got to 7-45. My last CO PB came a few months later in October 2021: a Triple Crown run to 7-55. Since then, I've never gotten back to 7-55 - until this run.

The Overlunky watermark was added for April Fools' Day. Convert 0x134d811 to decimal and you get 20240401 (2024-04-01). Every clip (besides the audio mentioned below) is from my real first ever CO clear.

#spelunky2 #cosmicocean I finally did it! - Spelunky 2Legendary Snack (Seeded)Gugubo2024-03-27 | A combination of lizard snack and legendary meal. Only about 1 in 400 seeds* have a dwelling level with the right conditions. This run is seeded, using the seed BEE71E85.
Legendary Snack% Definition: Feed 7 dung beetles to a single lizard.
*I sampled about 5831 Dwellings and found 6 1-1s, 8 1-2s, and 17 1-3s with at least 7 dung beetles. From this I get the following chances (with 95% confidence) of at least 7 beetles in a level:
1-1: 0.02% - 0.19% 1-2: 0.04% - 0.23% 1-3: 0.15% - 0.43% (Although, according to the level files, the dung beetle spawn rate stays constant throughout the Dwelling.) 1-4: ~0%
Added together, this becomes 0.21% - 0.85% per Dwelling. The chance of having at least one lizard per level is around 65% - 83%. Thus the total chance for at least one lizard and at least 7 beetles in at least one level per Dwelling should be around 0.15% - 0.6%.
(A more accurate number could be determined with a larger sample size, looking at each level separately (because, for example, 1-3 has a higher chance for lizards than 1-1 or 1-2), and multiplying the probabilities together correctly.)

The theoretical maximum appears to be 46.53 tiles. According to MauveAlert it's 56.53 tiles; empirical testing by Cosine shows it to be around 46.5. This implies a 10-tile-error in Mauve's calculation resulting from the order in which the player velocity is set and the gravity is applied.

Low% Keyamat Definition: A run ending with the player completing the game following Low% restrictions. You must find and carry the golden key from the Dwelling and cannot drop it, except to deal the final blow to Tiamat. Dealing the final blow to Tiamat by any other means is forbidden.
Version used: 1.27 (in most of them, some clips might be older)
#spelunky #keyamat Trying to get a Low% Keyamat run - Spelunky 2Turning Olmec slow in under 2 minutes (Speedrun) - Spelunky 2Gugubo2022-09-28 | Far cooler than any Olmec-push-block-interaction from Spelunky HD. :^) Skip to Olmec fight: 1:40
Explanation: Due to weird interactions between Olmec and the push block he becomes slow. This happens in the video at 2:11, but you can best see it at 2:44 when Olmec has more room to move. Anything after the first push block hit is just showing some weird interactions. At the end I get crushed, not by Olmec jumping, but by uncrouching (bonus jank). Also check out that sick double double arrow whip in 1-1.
This speedrun was invented by remy and it's a cool opportunity to show off the three-bomb-quick-first-phase-Olmec.

#spelunky #speedrun #paranormalInvestigator Paranormal Investigator% Speedrun (First Clear) [25:59.100] - Spelunky 2How To Deal With Powder Keg Hermit Crabs in Spelunky 2Gugubo2021-10-05 | I started working on this video back in February and only just now finished it. The reason for doing it was really to find out what makes powder kegs explode because it sometimes seemed arbitrary. The short answer to what triggers the explosions (see 1:44) is: It depends only on the velocity of the item hitting it. Additionally, it only depends on the x-velocity if it hits the sides and only on the y-velocity if it hits the top. For the sides, anything with an x-velocity greater than or equal to 9 tiles/second will trigger an explosion and anything hitting the top with a y-velocity of greater than 15 tiles/second will trigger an explosion. Those are from tests in Overlunky where I checked for velocities around 0.001 tiles/second slower or faster than the mentioned values.
