What?! Insanely cool! I've been wanting to learn GB Studio recently, but haven't been able to get it working on my device, and now you're making me even more sad that I haven't been able to get it working!!
The style is awesome, both the sounds and the art. The cutscenes are super cool, although there's maybe a little too much exposition in the start for me personally. I also wish that there were some hearts or something instead of just one hit killing you, or maybe make spawn points a little closer together. As someone who is terrible at everything, I ended up needing to go through decent sized sections more times than I would've liked.
But overall, this is an insanely polished and ridiculously stylish little demo. I love it!
