I read all feedback about the game and started to work on remaking rebirth system. It will take some time, but hopefully it will come soon. Also, I tweak some upgrades to speed up game start, by tweaking Gunshot upgrades, and increase efficiency in late game by tweaking Lasergun and Spikes upgrades

New content is delayed now, but it just another chance for me to balance it better. Thank you all for detailed feedback!
