If you didn't know, me (the original Mibibli dev) and my partner have been making games together. And here's our most recent game, which after all these years is the most like a "spiritual successor" to Mibibli's Quest out of anything we've made!! Check it out and wishlist here:

If you liked Mibibli's Quest you should like Stardust Demon too! There's differences for sure; Stardust is more metroidvania than megaman, and the art style is more polished. But there will be big similarities, with it being a game that mostly plays like a traditional action platformer where you collect new powers. There's also fun surreal twists and turns, nice vibes and weirdness, a main character that's a cute little creature, etc.
If you like our work, wishlisting really helps us out and enables us to do more. Thank you!!
