hello! it seems like you get upgrades a bit too often, especially later on / when having a god run. to counter that, and use upgrades more as rewards, i made these changes:
rockets now give score based on how hard they are to kill and not their size
the additional score requirement for every new level is doubled (new level before: [x score] + 5 score per level. now: [x score] + 10 score per level)
emp effects now remove shields off shielded enemies, but don't freeze them on the first use
the emp interceptor highgrade now requires 25 energy instead of 10
added new upgrade "directscore"
fixed the issue of the vignette effect hiding buttons in the settings menu
