This was a pretty interesting take on the grow theme, with enemy hordes growing stronger and stronger as well as your own character and defences also growing throughout the game. I also liked that you could level up quite quickly and pick a new defender quickly - it added to the sense of progression and accomplishment while playing the game. I also liked the magic woodland theme of the art. I think some more detailed controls and instructions could help - I wasn't sure how the game was supposed to work at first, but I managed to figure it out over time.
