ok i don't know who made the mod but i have some feedback:
Single Star. for some reason playing Classic with only this enabled makes you do SSL for eternity but Free Play cycles you through SSL, WF, and BITDW. I would have liked to see Behind Chain Chomps Gate or Shoot Into The Wild Blue or even Wallkicks Will Work in here but you only got the three stages as far as i know.
Platformer: while yeah I guess using Rainbow Ride is a good way to easily do this but why not more levels? or even custom levels? like i know this is supposed to be like WarioWare where you have a short amount of time to do a minigame but you could literally make obstacle courses and it would still be fun. I mean it is called "Platformer" and not "Jump 2 or 3 Times"
Red Coin Hunt: good idea, you did it pretty well but I suggest finding 3 small levels and then hiding 8 red coins around the map. for example, Whomps Fortress is pretty small and you could definitly have a section in the water or something where theres 2 red coins but you spawn at the whomps or something.
Logs and Pound: ok so i actually read this wrong multiple times and it wasnt till i went to read its description that i learnt the objective wasn't to run around the posts like you would for 100 coins but instead to ground pound them a single time. i already feel most speedrunners are going to make the same mistake, read "round" instead of "pound", and constantly die to this.
Through The Ringer: so this is the one where you have to fly through the air and through rings. pretty good so far. but i assume most people are going to NOT be playing this alone so i can already imagine someone ground pounding people and then everyone dies. unless you have a solution for this already, i don't think this minigame is suited for multiplayer.
Overall Statement: great mod! just please make the objective text more obvious. i can't tell you how many tetris games i lost because i had no idea how many lines i needed
Platformer: Yeah, more levels probably would be nice
Red Coin Hunt: Same thing
Logs and Pound: I don't think I've seen anyone make that mistake more than once. Based on your other statements, I think you have your DJUI scale really low or something and that's making the text too small to read.
Through the Ringer: The way multiplayer mode works is that 70% of players have to win the minigame by default. In large player counts, this means a few people can fail and still win. You also don't interact with each other, so you won't get in each other's way.
Regarding overall statement: Like I said, I think you have the DJUI scale really low. Not only does the text fade in from the center, but it's constantly displayed at the top of the screen.
