Stickman Merge Halloween combines the merge mechanic with a stickman battle: identical fighters combine into stronger ones, and the army you build fights the horde on the other side.
Merging costs you a unit while you do it, so the recurring decision is whether to hold the line with numbers or gamble on quality.
Two identical fighters combine into a single stronger one — trading quantity for quality, which is the central decision each wave.
Between waves. Merging mid-battle leaves you a unit short at the moment the line needs holding.
Yes — drag to merge. Nothing to install.
