Thank you for giving the game a go and testing it in specEmu and inkSpector. I suspect the invisible sprites at the top of the screen are a memory issue rather than an attributes one. I'm currently fixing a couple of minor bugs, but the skull code could be optimized a bit better (a lot of duplicated code). I'll see if I can reduce that down and hopefully that'll get rid of the issue on the top lines at the same time. I should have an updated version later this week and hopefully it'll fix that issue too. Thank you again for having a look.
