It would be helpful if there were some sort of indication when you hit a fly so that it is clear that it is taking damage. Also an indication of what spell you have selected. There's a bug when you stand at a certain angle it seems like the spells somehow get stuck behind you or just don't reach the target. That made it a little difficult to keep up with the game. I think it would also be good to shorten the time it takes for the flies/ plant needs to initially spawn.
