Well, the art is very good and it’s a solid start! Obviously it needs a lot of work and there are a lot of plans which is good to see!
I would take out the camera zooming in and out. Leave it all the way zoomed out - or find a happy medium. When it’s zoomed in it feels claustrophobic. You’ve got the visuals, so let players see the world around them.
With as many people working on this, it’s a shame there isn’t just a bit more content. I would have added at least a little bit of area to explore. Perhaps even at the top of the boss “chamber” a reason to use the double jump to escape into an area beyond that. I don’t think that would have been too difficult.
We hope we have a good start to something bigger too! Won’t you please try our game out, rate it and let us know where it could use some improvement or where it could go next? Thanks!
