Hey, that was fun :). There was no sound in the game; I don’t know if this is due to the web emulator being strange or if there isn’t any sound. I would’ve loved some glass smashing sounds as the gerbil hits the test tubes and stuff.
I think it’s really impressive that you’ve made a game for an ancient system in such a short span of time; I’ve not looked into genesis development before but I imagine it’s pretty difficult, so pulling together something playable in that space of time is impressive to say the least. The boss battle was fun, a bit of a memory game, but satisfying once I beat him for good :). Really cool game, well done.
