And I may not want the name "Triton" :) You should ask for a name at the beginning and this name must be replaced with "Triton" on the cutscene texts. Also you may put up some ranks just to give players the feeling of they do something important. For example, u start as a junior and at the 3rd lvl u receive a message that u are promoted to captain and now authorized to use more advanced weaponry, thus unlocking new weapons or armors. And performance specific ranks like "ace". This is not achieved by just passing through lvls but killing 100 enemies, double ace for 200 enemies.. By the way, put some pics for those upgrades that visualizes u bought something strong. For example, lvl1 armor is an img of a wooden shape and lvl5 iron, lvl8 titanium... up to your creativity! Don't waste the potential on this game ;)
There must be ship specific weapons to buy, not only upgrade. For example, when u choose stable ship, it's ok if u upgrade your cannon but there can be another cannon like warcannon thats damage is equal to lvl5 normal cannon and worth 15000 diamonds which is cheaper than upgrading normal cannon but a little hard to get cause you mustn't spend on upgrading and larger ships will give u the edge till you get your warcannon. Or some completely different weapon to buy for 20000 diamonds like sonic cannon that gives little damage but reflects the small enemy ships backwards, or an electrical gun that disables ships for a short time (1 or 2 seconds). This way, gamers will have the chance to customize their war machine and will really own it and try upgrading it to the edge that improves your games playability.
game started smoothly but started lagging greatly after lvl 22-23 where the long destroyers (or what u named them) started to come. Besides lagging, it nearly locked up my browser. My computer is really high on performance so i think this may be a bug. But gameplay is great and this looks like a beginning of a great defense game ;)
game lags at higher levels and i couldn't see a "detail" option. I guessed it was "q" key but it ended my game, noone seems to read the info about q button on the difficulty menu, and we don't have to. This is global man, q changes quality!... 2/5
