This looks amazing! And as a fellow Gdeveloper I do appreceate that a lot!
However, it is quete confusing at times. I don't seem to find any indicator of how much health I have left. Apart from that though, this is an amazing game! It's got amazing graphics and is very well polished.
One thing I'd like to ask, if you use Z as an entry method, please also map Y to the same function to accommodate for different keyboards.
