I think the idea is cool, but this is really rough, ha.
The UI elements are kind of a mess, clipping all over each other and changing their appearance and location all the time. More crucially, in the game itself, the strokes and score blocked the field and there's no way to shift the camera. Just had to take leaps of faith.
I thought it was funny that you could smack the goal out of the way, but the score detection seemed a little wonky if I tried to, say, beam the ball into the net.
Good first effort! Nowhere to go from here but up!
