This is what was actually changed during the April 1 update :)
BUGFIXES Holocoins no longer clip through the map
Fixed some JP translation errors
BALANCE CHANGES
Decreased ERB's damage on hit (she now takes 9 hits to destroy a basic a-chan)
Buffed Botan's attack speed a bit
Buffed Flare's attack speed
Buffed Luna's attack speed
Luna now tries to shoot robots in adjacent lanes as well (whether she hits them is still random of course)
Buffed La+'s attack speed a lot (chargeup time reduced from 14s to 10s)
MISC
Added "Oh hi" to Mumei's voicelines
