Combining the tanks to power up is a really unique concept and the animations for merging are amazing. I had fun with the game however I got stuck rather early, as soon as you need to leave one tank behind it feels really punishing and a lot of jumps suddenly have super precise requirements otherwise you won't make the other side. When you fall off you get re-spawned at the start, however when a single tank is behind a lock (such as the blue first lock) there is no way except for a full reset to get back going.
Like the concept a lot, could use some work on the kinks in the game-play aspect.
