So, I had a great time, but also, this game is legitmately weird.
Not like bad, but just in the sense of.......
It looks like a Puzzle Bobble-like.
But... the main mechanic of puzzle bobble is pressing left and right, and aiming your bobble cannon.
Here in orb tower... you target with the mouse, and the game figures out the aiming for you. the choice of what to aim at as yours, but there isn't so much of a dexterity game to line things up. Which is... neither good nor bad, but just means that like... even though the game LOOKS very similar puzzle bobble, the actual skill and gameplay is very different.
