Since it seems we kill the fun by letting you die the first time you die we'll look in to adding a couple of lives :) We might nerf the shield because of this though... let's hope it adds to the fun!
Thank you all for your feedback! The most important thing is your experience. We're very interested in hearing what you think is good/bad and where there's room for change or improvement. Thanks for playing, it's thanks to you players that we make our games!
