I see that you are still setting up this game categories and need new ideas. Here are some.

1. infinity time wave 25 (no skipping waves) starts when you spawn into infinity time and ends when you reach wave 26, (mabye ends in the treasure room)
2. infinity time wave 50 (no skipping waves) same rules as 1 but when you reach wave 51 it ends. 1 and 2 will be sorted by the players.
3. delivery goat (all missions) starts when you choose the first mission and the timer starts and ends when you get the complete on the last mission.
4. pizza chomper (all missions) same rules as 3.

We can make them as All misc. categories, Delivery goat% and Pizza chomper% are good categories. With "infinity time", 25 wave and 50 wave can be subcategories to separate them from the runners that do 25 waves and 50 waves. More will be added soon and if you like, I'm offering you a spot on being a mod on the leaderboards.

I also thought of more.

1. flag of power (beating the boss wave) will start when you are teleported to the middle and ends once you beat the boss wave.
2. mystery of the crystal brainz (installing mission) starts when you spawn and ends when you reach the portal room to replay in hard. In both normal and hard diffiulty.

Also you should specify the rules more like are unlocked characters, glitches, hacks, if they are allowed to be used in speed runs because there is only a video of you with nothing unlocked but you already completed the missions.

And I will take the mod on the leader boards and even attempt to set some speedruns.

I was thinking that upgrades and unlocked characters should be allowed, maybe separate it with no upgrades in two subcategories but I don't think that would be a good idea. I will add an option when someone submits a run, there will be an option where it says "upgrades" or "no upgrades" before submitting. I will also update the rules for no Cheats or/and hacks.
