I have been on level 2279 many days and I don't think this level is possible 14 flowers, 25 firecrackers, 70 waterdrops and 220 suns with 22 moves. Needs more moves or little bit less everything, specially flowers.
On this board you have to stay a step ahead by always being mindful of the conveyer belt and the next move it will contribute to the board. Bad luck also factors in lots, the firecracker always seems to wipe out the water droplet needed for the seed.
