Fantastic entry and in my opinion the best implementation of the theme, you didnt compromise fun game play at all. The fact that you as the player are indestructible but taking damage may lead you to hurting green ball boi was great, I felt like I had responsibility to not harm the green friend. I found myself hiding in the corner alot since when I lost control it was the safest place to be to keep green boi safe, longest time was around 115s. The game really makes you feel like the hulk fantastic! The sound design and visual change when losing control was spot on too.
If I was to give suggestions on improvements I would have like to see the personalities played up a bit, maybe something as simple a smile on greenie. (not that its easy during a jam). The simplistic graphics worked really well and probably let you polish it to hell, but I do think having a bit more character would be interesting considering how well the feeling of "Protecting a weak wholesome boi" was, green felt wholesome because the hostiles were none hostile to him.
You guys nailed it in my opinion, great work!
