My team and I had a communication issue during the jam where I thought the way levels worked was as soon as you clicked "Start" the bullet would be shot, but at some point, we changed it to the player needing to interact with an object to trigger the bullet being shot. I felt that it defeated the point of having the time stop entirely but it was too late to argue over the design so we just kinda patched it together right at the end. Also when you say "The others being on ice when you push them makes them feel hard to control" do you mean when you are in QuickTime or in real-time?
We do plan on continuing working on this because it's a really fun idea and personally I like playing it. We'll probably update the page with a newer version after the jam ends tonight. This morning I took like 30-ish minutes to go in and make the game closer to what the team wanted.
