I like the concept :D
Thanks! I also included some upgrades of speed, damage taken and maximum health. You collect fish and buy upgrades which has incrementally increasing price. The game is very hard and probably I will create only 4-5 levels for now. Also have added a jelly fish enemy and currently working on mad corals enemy which acts like spikes turning on and off over time :D This is my first game jam and I am really excited to take part in it.
