Upgrading

To ensure smooth gameplay progression, upgrading equipment becomes increasingly important in Green The Planet 2. Players can upgrade various elements, such as the radar for summoning more comets, the collector for earning more Energy while the game is idle, and the weapon and unit levels for faster comet destruction and increased Energy generation during active play.
Upgrades should be prioritized based on their affordability relative to the current Energy income. Investing in upgrades that seem "cheap" at the moment is generally a reasonable approach. It is worth noting that money spent on the weapon is refunded once the planet is "Greened," allowing players to experiment with different weapons and freely upgrade them.
However, it is advisable not to spend all Energy upon starting a new world, as weapon parts need to be repurchased, although comet difficulty resets when transitioning to a new planet.
