Uh... Okay, I tried to comment, but I was way over, so I'll get to the point:
After playing it more, I love this game. It needs work though.
(1) AI: Computer can't use grenades (or chooses not to) - fix it.
(2) Classes: Get us some namin' goin' on. Also, perhaps more options for customization as you gain levels (increased move/range/regen/stunning shots, whatever, just some unique ideas).
I hope to see this game get a bit more development, then it'll be a solid 5/5.
I've played this game on a different site previously, and I've -never- had so much trouble with lag. Seriously, I'm completely unable to get even half of the coins that drop, because they disappear too fast. If the lag were fixed, it would be fine, but as is, I really would rather just go play this somewhere else.
Definitely needs a "mute" button. The lives though are fine as they are - it's pretty unforgiving, yes, but you quickly learn to avoid the sharks (like... after you lose once, you should have it down), and there's a save/load with no penalties. Lives should -not- be an issue (unless you decide that you're -better- than the sharks).
Excellent, and I only had an issue with lives the first time - after that, yeah, I figured it out.
Don't quite get what seagrass is for yet though.
5/5 - Excellent work.
I like it quite a bit. Simple and enjoyable - exactly what I look for on Kong (instead of drawn out and boring). Up to level 14 and haven't really felt "challenged" yet, but had a blast the whole time.
