Hell yeah. Monochrome art style is very rare to see nowadays and I can see that it's been done really well here. It really does deliver that "Long dead, infested world" the game is going for.
It was worth it, short, concise and enjoyable. Kept me hooked till the very end of it. I also loved how "Unstable" was delivered in the form of "debuffs" that were different throughout the game. If you guys are making this a full game, I'd say go for it. With a bit of polish and by introducing more ideas into the game, you can get to places :)
Now I know the game jam was only a week long but... pardon my nitpicking :)
The AI needs rework, it's usually good but it kept eating at the wall for me once, probably not a good sign from a game dev perspective. In longer levels it can happen more often.
The combat can also be more varied, in longer narrative platformers like this, things can get repetitive very fast so its good to remain creative so you keep on that hook.
Looking forward to how this turns out :)
