Very interesting and ambitious game! The art and the music are also very well made!
I used to use Gamemaker Studio, so I really appreciate the effort needed to make a game that relies so heavily on UI with it.
Some feedback on making the ux a little friendlier. Maybe you already identified all of these points:
- The scrolling should be limited so that the player can't "overscroll" on both directions.
- It might have been a time limitation, but I think maybe the match tapes should be arranged on a scrollable grid instead of a single column? That way you could show more tapes before requiring scrolling from the player.
- You could also have the game show the results of a match right after it's finished so the player doesn't have to alternate between tabs after every match.
Also, the game goes into a black screen when trying to read the results of my 8th and 15th match. My login is Agnimis if it helps you debug it.
Other than that, I am very impressed with the amount of systems and interfaces you managed to put out for the event. Nice job!
