when an underground tunnel is used it should really be highlighted as you can so easily get stuck in the black underground areas. also when you beat the snake the map should show where the remaining mushrooms are to make life easier for you.
at least 2 of the scenarios are impossible unless you cheat. especially with the money you start with on them. and the sandbox 5k badge is WAY impossible.
theres another bug. you can actually get stuck in the invisible underground tunnels and because you can't see where you are it means you can't get back out again.
the game should remember the last reef you were on instad of making you restart from scratch. also is the reef with the oil spitting monster even possible? its not like you can hurt it or slow it down. i assume thats the final level?
any1 who doesnt include a restart button doesnt want you playing the game more than once. and its not very playable to be honest either. difficulty ramps up way too fast and the weapon you get is rubbish
