I'm personally loving freaky fruit paired with on-fire hydrant so far. I've yet to make full use of meteor trampoline but it's great for when people lose invincibility on the ledge and you just up B on them. Also, for on-fire hydrant, the sourspot tips of the flame that do 4% are actually great for hit confirms into KOs. Something I experimented with just now demonstrates this.
This does in fact true combo and as you can see, it KOd him at 80% which is amazing for Pac-Man. Granted, there are other factors that could've possibly changed this but this should be a good display of the power customs can possess in Pac's future.
Something else you can see me do here is utilize the empty fruit charge from a dash into the KO move. This is something we should incorporate into our games more since it allows us to use any of our standard moves almost instantly from a dash rather than shield>shield drop or waiting for the skid to end. It has a lot of potential when paired with hit confirms and the input is dash>B>Shield (to cancel) with the latter two inputs being done quickly. I'm aware it's been known but I've never seen it utilized extensively. Something else you can do with this is dash with a key in hand>ftilt with key in hand (input being hold down on control stick and C-stick forward) then read the airdodge for a key throw. Basically, this gives us better means to approach.
