Merge Knife is a free arcade game developed by WeDoYouPlay for Android devices. The game combines a sticky arcade game with knife crafting mechanics. The objective of the game is to throw knives at enemies, earn money and spend it on upgrades. Every 5th level, there is a unique boss to defeat.

The game is easy to play, you simply tap to throw the knife. But be careful not to hit other knives. To merge two knives, drag one over the other and get a new one! The game offers an exciting experience with familiar mechanics and knife crafting.

Overall, Merge Knife is a fun and addictive game that will keep you entertained for hours. The graphics are well-designed, and the sound effects add to the overall experience. The game is suitable for all ages, and I highly recommend giving it a try.
