I liked the game, a simple little score attack with some cute mechanics.
Personally I would've liked to see perhaps alternately keyboard shortcuts to the upgrade so I wouldn't have to to swap between the control of my heart as much. But it worked well enough. And maybe some more emphasis on the disconnection? Because it mostly boiled down to connecting more, and having to save up for an extra turret that you can then somehow miss out on feels a bit off for a game.
That stuff aside, it was very solidly made, fun to play and very polished. Great job on the gamejam and keep up the good work!
