So I finally try your game xD. My score was : 3,21min.
First of all: Awesome idea. Mixing a shooter and a platformer is great!
Plus, your really nailed the physics. The jump and the shoot mechanic work well. The air control is perfect. It's not too hard to go where we want.
For the graphism, the frog is really cute, particule effects are cool. Maybe a more detailed background could be better but in 48h it's not a big deal.The sound design is cool, maybe in a future version, you could add a music.
To sum up : GG! One of the greatest game of the jam. If you can add more levels ( and maybe more complicated, because the difficulty curve is perfect but no enought hard for me xD).
