Thank you for trying out my game Nerien! 💯
Do you mean the level with the gate and turret?
The one where there's two turrets one facing from each side of the bridge to the gate, and a guitar in a table in the park. XD
Aha, the hint is: Saving goes a long way.
And you don't feel particular thirsty yourself on this level.
Aaahahah I see, "Don't drink the Time Juice"
