If no one does it then save the health/energy/shield power ups for bosses and just get the shield power ups during them, once you have all upgrade points with the right upgrade setup (lvl 3 hyper shot with 10 dumb or homing missiles depending on how the boss moves) you can kill all the earlier bosses before the 3 shields even wear off.
5/5 great game. My only complaint is that you need to kill all enemies + avoid all bullets for grade A, killing enemies isn't bad but avoiding bullets is impossible for later levels without any form of cheating, the hit box is just too big to efficiently avoid some attacks, let alone bosses taking a while to kill.
Here's how to do lvl 63:
G - right. N - left, right, enter, left, right, enter. G - right x3. P - right, right, left, left. O - left left. R - left, right. M - left, enter, right. Y - left x2, enter, left. K - left, right x4, left x2, enter, left, right. G - left, right, left, right x2, left x2, enter, left x2.
What's the point in random waves when you can get absolutely owned if unlucky? I made it all the way to day 35 without dying and always having full HP by the end of the days then I suddenly die, I restart it and win the day on full HP again. Pathetic if your playing on hardcore.
I really want to like this game but it's far too unbalanced and often relies on luck, I'm giving up with it now now until (If) badges and tweaks are done, day 27+ took a massive difficulty jump, had very few problems until then with only 4 game overs in total, now I'm up to day 29 and had about 10 game overs since day 27 without even coming close to winning day 29, I keep dying on wave 3-4 out of 7, how a game like this can take such a huge difficulty jump is beyond ridiculous. Taking rating from 4/5 to 2/5 until fixed. Oh and for people wondering about the chicken lover medal, did you get level 31 chicken or level 30? You need 31 for it.
Leech mod is completely broken, I swear I wouldn't have made it past day 15 without it, now I'm up to day 25 and it's sure helped me survive through each day, has anyone got this far without it?
So with 95% of the people having trouble with the game then the other 5% only coming out with comments such as "You suck at this game" etc. then why not give the rest of us some advice? Surely it's nothing do with our skills in aiming and shooting because I doubt 95% of people would have trouble with that.
@ringhloth, how's is it not the games fault for being hard? In your words then there's absolutely no game in the world that could be considered hard when that's obviously not true, if the general consensus find the game hard then the game is hard despite wether or not the minority of people are good at it, if they find it easier than most people then good for them but it doesn't make the game easy.
I absolutely hate the idea of accuracy, I've failed day 7 four times because I simply can't hit the enemies and get overrun, I'm using Militia with the starting rifle because I haven't looted any or found any in the shop and even when the reticule is over the centre of enemies bodies it can miss often, very annoying when trying to take out those tiny butterflies and sometimes it can even miss the bigger ground enemies, just missed one of those orange axe wielders 3 damn times in a row which caused me to fail again. Quite fun but the most annoying game I've ever played on Kong. 2/5
Here's a video I just made of the strategy I mentioned a few comments back http://www.youtube.com/watch?v=seGkuWkQuP4, with it you'll easily glowing frame any level.
Once you get the skill that reduces cost of gems/combining then just keep combining 1 gem into grade 1 gems, each time will add about 3 damage and slowly increase bonuses but it will also increase range and shooting speed dramatically over time, get it with splash, mana drain and slow/reduce armour and you'll completely destroy anything with only the 1 gem, works early in the game (Just beat the 2nd epic level) but I'm not sure about later on.
