Well done on your first game jam entry!!
Cool game. It reminds me of the original Grand Theft Auto (but.. with water!). Nice take on the concept too. Love the little fire orbs~ (I got splatted by them... a lot!). The slight movement of the world makes it feel alive~ Nice game title, too. Sounds like an 80s super hero X)
Single favorite thing about this game: The fact that you can use the water orb attack to strike lots of enemies in a line. I expected it to explode on the first one, so that was unexpectedly cool!
Constructive feedback: It might just be me missing it, but the 'HP is power' theme was very obvious to me. I died instantaneously when hitting the flames, and didn't notice any obvious changes to power/speed/attack range, etc. Like I say, might have just missed something there!! Also a checkpoint system would work really well in this game, so you don't need to go all the way back to the start every time. (Sorry if there is one and I just didn't get far enough) :P
(Just something random I thought of: This isn't a problem for me personally, but some photosensitive players might be affected by the flashing background and rotating screen, so if you chose to expand on this or make something similar, a setting to turn these off would probably be appreciated by some.)
Really good work - I look forward to seeing more jam entries from you ^_^
