I have never before played a game where the edge of my screen is my main opponent. Perhaps dragging in the direction I want it to move rather than the opposite could have solved this.
This is certainly an interesting idea for a game. I like that the character stops falling when you start lining up your next shot, but starts sliding again, so you can't just aim forever.
I was hoping there would be some more challenging levels near the end, but otherwise the game is a good length for the mechanics it is showing.
Overall, I enjoyed playing your game. Thanks for participating in the jam.
