Tips for impossible badge: First of all, missiles are your friends. You can sit anywhere and they'll do all the aiming for you. Next, energy absorbers. Trust me, you'll want all the overload you can get. Third, time slowing overload, always handy. Can't go wrong with extra boss damage too. Go through each level the whole way before going for unharmed, so you know what to expect. Despite being counter-intuitive, lag is your friend here. The slight drop in fps you get while engaging time slowing could save your ship. Last of all, you're going for unharmed. Pick the interceptor, its low health doesn't matter if you aren't being hit. And of course, if you're finding it hard, pick a lower score multiplier, that doesn't affect the badge.
Just so you guys know, the 10k coins achievement doesn't mean pick up 10k coins. It means receive them. So at max upgrades, just go 50k distance. Easiest method- use launchers until you're about space height. Use rocket. Continue to use launchers. You should reach about 30-40k without hitting anything.
Why does destroying their castle/tower/whatever not do anything? It seems to me they shouldn't be able to resupply troops then, because that would make sense. I destroyed a tower of one guy in two or three cards, and then he got out a load of purple cards and decimated me. Not terribly balanced.
Not great. The graphics, while cutesy, get irritating in that the hitboxes don't match the images very well. They also seem to have a bit of a memory leak, with a lot of lag. The cash is not well balanced at all, you can go as many as four or five launches with next to no upgrades. The minigames aren't terribly clear on what you have to do, and the win/fail stamps are more irritating than useful. Similar to burrito bison you say? It's not a copy, it's similar, but it's a launcher game. There are only so many variations. Music: The theme seems amusing and cute at first, but rapidly starts to grate on the ears, mostly due to the intermittent high pitched whine in the background (but to be fair, you may not have noticed that). The music is alright in the attempts to change, but it's not great.
Overall, I'd give this a 2/5. It's alright for a time kill, but it's nothing new, special or even really attention worthy. There's much better work out there, including by the same author.
Since the top comment has a good list of all of the skill tasks, thought I should add the one it doesn't: a passive skill, the ones that give things like immunity to sleep/poison, bonus to hp/mp etc. They improve at 1 point per battle, and are typically around 40 points to master. They are the hardest to master, although arguably the best. They, as far as memory serves, are only found on accessories. And every battle counts as a point, regardless of how hard. So, if you're stuck, have a piece of equipment with a good skill, but another with better stats, go to the woods and grind easy enemies until you master the skill.
Game dynamic is fine, not as well streamlined as the previous epic war games, but not bad. Unfortunately, the addition of time recharging energy takes away from the game. The normal versions usually took hours to play anyway, making it so you can only do so much without running out is a tad ridiculous. I understand it's to make some money, but I mean, how do you expect people to finish?
