Phew! It's certainly been a while since I've posted about the progress, but things are getting done albeit slowly.
I've made a video containing some of the new things I've added in the past month or so.
The shield is getting closer to being finalized and it now pulls in the item drops. The water has been added and tweak into something that resembles liquid. The movement feels pretty good now, entering and exiting the water. Also and jump extension power-up has been added.
A few small things have been touched up, like the hover flame and the energy drop.
I'm going to continue working on the shield, especially the mechanic behind how it will absorb projectiles, and then work on enemy behaviours.
