This is a game with some nice potential! Congratulations! I like the core mechanic of shifting the view. And the aesthetics work really well. Bravo, nice complete work!
I have a thing to say about the controls though. It mostly has to do with the view rotation (ijkl). First of all, I think it's just weird that you are allowed to rotate the view outside the Shift Mode. It feels odd and it should be restricted to Shift. Second, I think rotating in general leads to some weird situations... I believe mostly rotating up and down are problematic. Like, you can see where the target is, so you enter Shift Mode and you adjust the view with OU and IJKL, so that your ball effortlessly drops on the target.
Hope you may find this useful. Greetings.
