Nice job, I had fun with this! The medicines being toggle-able is a really cool mechanic. It was cool to get the second medicine and then un-toggle the first to continue progressing. One of the cooler implementations of the theme I’ve seen!
I found the spikes to be a little frustrating. I also accidentally reset my progress to 0 because I died to some spikes, and then accidentally hit A at the start menu, which defaults to ‘new game’ (maybe a “continue” option would help here, or maybe the death screen could just respawn you at the checkpoint by default without having to load game).
It was really satisfying to get the upward bubbles and finally have a good answer to the projectile enemies on the ceiling. I found it hard to play with a controller initially because it’s tough to aim with the right stick while jumping and shooting at the same time, but the upward bubbles made that a bit easier.
I wasn’t able to finish it but this is just a skill issue on my part, I’m terrible at navigating big maps and I really appreciated how big and interconnected the map was.
Nice work!
