I'm a big fan of scores in jam entries, but in this game it wasn't particularly difficult to avoid the birds or falling spikes, so I think I could have gone on forever. I love the idea of one of the player's projectiles being a moving platform that they can ride, but in the current version of the game, I didn't find much purpose in using that given how much mana it cost.
Overall, though, this feels like a fine entry :)
