This is a simple mod to slow the stage timer down and allows players (n00bs like me) to gather more powerups and (ultimately) slaughter more enemies and clear more stages.
This is the BepInEx version. MelonLoader version is available here
Download the mod
Install BepInEx 6 to Megabonk
Unzip and copy the enclosed "SlowerTimer.dll" into <steamapps>\Megabonk\BepInEx\plugins
