Really great concept and idea, but technically not quite there. I'd really like to see a version of this that's had a longer development time. The best part for me was when I went pretty far into this underground part, drank a potion and then got so big I busted out of the entire dungeon.
Unfortunately the game froze at this part, but I think it is such an amazing idea that you spend ages going through a complicated dungeon/puzzles etc the end it all by just going full giant hulk and smashing out of the entire thing, destroying it in the process.
Overall, a really great concept but unfortunately not quite there in terms of gameplay. I really hope you turn this into a full game.
