Nice job! Thank you for playing our game!
I appreciate the feedback concerning the shop and agree that making upgrades more accessible early on would improve the gameplay. I also like your idea for the stone trolls coming back after a certain period of time to give the player a reason to smash them.
For a future update, we are considering making the sunlight drift in and out after a period of time so that the player can't farm light and shoot all the trolls. But to your point, we are definitely wanting to improve how the sunlight works overall.
Thanks again for this feedback and we're glad you enjoyed playing!
