The Ukrainian government and military needs to figure it out fast before they become a land locked country. The Russians have made some serious gains along the southern front and pretty much secured a land bridge to Crimea. I wouldn’t be surprised if that was priority number one for them since they had to secure fresh water to Crimea. Odessa is going to get sieged like Mariupol and if that happens that’s a major blow to the Ukrainian economy. They will lose access to all their ports.
A sizable portion of the UA is in serious danger of getting encircled in Donbas. If they do a tactical retreat to the Dnieper I wonder if this when we start to see the Russian Air Force? All these experts have been perplexed at the lack of a air campaign during this operation. If the Russians put them in a cauldron we could see the 2022 version of the highway of death.
The eastern front looks hopeless, I'm no military expert but it seems that a careful retreat to Dnipro and then regrouping west of the river looks to be the best solution to avoid too many casualties and reduce the number of fronts.
I'm not sure Ukraine cares about access to the sea as Russia probably already has superiority there. Above all as Transnistria may assist Russia and make Odessa encirclment and takeover easy. There are already Russian ships at the ready there in the Crimea sea.
The supplies can easily come from Poland or Romania so it looks like the Lviv-Kyiv connection is the most crucial line to keep in that case.
Doesnt look good overall but it was expected. Each day Ukraine resists and make it a grind is a victory even though Russia is obviously winning in the grand scheme of things. IMO, if they make it past a month with enough Kyiv, Lviv and enougj men left, it may start to look a bit vietnamese for Russia.
No money to fly, no planes to fly on, Putin not letting you fly anywhere 
Putin didn't think this through.
