This has such an amazing nostalgic feel, as soon as it started it just gave me such positive feelings. The gameplay is really novel as well; it starts out seeming very simple and quickly becomes more strategic as you have to predict where your princesses will bounce to after attacking. I wish there were more boss designs because the art is so lovely and I'd love to have more of a sense of progression. Only one tune but I actually don't mind too much since it fits the old school feel.
I do agree with some other people that a more in depth tutorial (or even more detailed written instructions) would be nice - I didn't realise there were weapon options and I also didn't realise that the princesses don't stay within their grid squares once the battle begins. The controls work really well, my only issue is that the arrows to switch between the princesses move around depending on the length of their names - would be good if there was a consistently sized text box that contained the names so the arrows were in a fixed position. That's just a tiny grumble though, overall I really like this and would just like more of it! Well done
