Really fun game, I played until a point I turned invincible lol, after unlock the speed upgrade, I stopped to read the descriptions of each ghost and I only would set them to random ghosts until one of them be a match. Never accumulate more than 3 ghosts using this strategy. As you can see, I played for some time, since I have upgraded the gain monie per match. The upgrades costs firstly 5, then 10 - 20 - 40 - 80 - 160. Well, addicting game as you can see lol, congrats for that! Visuals and music are really cozy and good.
