I was looking forward to this entry and I'm excited that it's playable now!
The artwork is totally adorable and the "recharging" is probably the cutest healing mechanic that I've seen in a video game in a looooong time.
The gameplay works pretty well most of the time, but gets quite challenging later on. A bit too challenging for my taste. I think checkpoints would be helpful, for example everytime you pass a flower. I made it to the room with the third flower and eventually gave up when I ran out of energy and had to start from the beginning again.
I think the flowers would also be good checkpoints from a narrative perspective, given that they tell parts of the rather emotional backstory. Having to pass them again after every restart kind of reduces their impact.
Still, it's a great adaption of the cartridge that is both faithful and creative. The soundtrack is also pretty cool. I'm looking forward to your future projects!
