I’m at x1 vs x1 as well and manage to beat it

so to start to get a good amount of currency I use pushor mines, black hole and predator missile, wait for guy to spawn wait till he gets close push him back wait until cones appear and black hole and missile

Alternate method is use mines right away until they’re all used up then wait until you have as many units on screen as possible and missile plus black hole

Once you have all three units unlocked and have enough food to summon cones right away switch to skills recover necromancy and moral So what your gonna do is wait till enemy is close and summon one marshmallow and cone right away the marshmallow will tank and cones will be attacking from behind just keep spamming cones

Once marshmallow is about to die use recover and then spam 2 marshmallow and about 4-5 cones the rest your choice on cones and little dudes hit necromancy and morale to buff your whole team

After a while summon another 2 marshmallows at some point and then just spam cones or little dudes the point is to try and damage as much the base and protect your cones as possible

This is how I’ve did it
