There are lots of options. The shaky effect was irritating after a while. Later on, I found that you can turn it off. Really well done on the user customization part. The graphics are well-polished and the sfx match the game well. Movement was smooth and I had no problems whatsoever.
But the time-slowing effect was really not so useful. It felt like it was kept in to just connect with the theme randomly.
Anyway, I applaud your effort into this game and well done.
Cheers!
