The demo was pretty cool! One thing that stuck out to me was the music, specifically the song on the title screen. I actually went back to listen to it more after finishing the demo lol. Being able to throw Alley was a fun mechanic, and going from throwing her to playing as her after she lands could lead to really interesting things.  My one criticism would be that the jumping and ledges (and how those two things interact) could use some improvement, but I'm sure you guys are well aware of that. Keep up the great work!
