I really wish I could give this game a better score.
It is a game, and you got in it within the time limit so congratz for that. It's a huge accomplishment just to get your game in, many did not.
I liked how each character had their own strength based on their size, the level itself is well designed.
However:
-The games controls are floaty and make platforming difficult. Not fun difficult, frustrating difficult.
-The game lacks any real UI elements to tell how or what a player should be doing.
-The buttons you stand on didn't make a noise or do an animations so I wasn't even sure if those things we working.
-When you're making a game with instant death pit falls, you need checkpoints. The last section of the game with the rotating platforms over the pit killed me a bunch of times, and spawning me back at the start, rather than right back at the beginning of that section was just wasting my time.(And wasting your players time is never a good thing to do)
All in all,
-You should be happy you got your game in on time.
-Your level design is on point, you just need tighter movement mechanics and more information for the player so they know how to play and what they're supposed to be doing in the game.
