I mean.. it was confusing at first, but I got used to it. This game is like Pokemon, and the "Pokemon" are called Osanai.
Here's a walkthrough for those who don't really get the game.
Ok, so basically when you click New Game, it will bring you to a screen with 5 Osanai. All of them suck, so choose the fire one. After that, you are looking at a battle scene with an Osanai named Bob. To fight, you click on the fist. To use potions, you click on the middle button shaped like a potion. To charge up your energy, you click on the third button. Click on the fist. Look at your attacks: Bark, Fireball, and Normal. Bark uses 1 energy, and it's a good attack for a starter Osanai. Fireball is your "stronger" attack, but bark is better just because bark only uses 1 energy and does decent damage over 2 turns, and Fireball wastes 2 energy and only hits like 4 damage at level 1, which is bad cause you only have 5 energy to start with. Bob's really weak so yeah. Damage is based off of your levels and your Osanai. There are 4 types of Osanai. Damage based, Defense based, Health based, and Balanced. Damage based is the only way you can get through the game without getting pissed off. Basically, whenever you level, you get more energy, health, and damage. Not so sure about armor though. Ok, you should be at a screen that shows houses. Click go back to map.
Now, you should be at a map. DO NOT PRESS ANYTHING. On the left of your screen there should be two houses. Click on them. You're back in the shops. Click on the opened door on the left. This is your Osanai page. You can switch around Osanai to use as your main one. The first Osanai is used in combat. Get out of there. Go back to the shops. Click on the door between the blue towels with random characters on them. This is the potion shop. I don't use potions. :P Get out of there. Go back to the shops. In the middle there should be a road leading to the forest. Click on the house right on the left of the end of the road. You are at the most useless shop in the world. The Kekyu evolution shop. You need money to get stuff, and a Kekyu. A Kekyu is easy to find because it's a universal Osanai, meaning it's found in all of the areas. I can't evolve mine.. It gets stuck. Get out of there.
Time to explain the map. The mountains (Top, Bottom left, Right) are made of mostly universal Osanai, the Osanai that shoot green stuff, and Wind Osanai. Strangely enough, the rarest Osanai in these parts is the Hantamago. Lots of health, really little damage. Really useless. YOU WANT TO GET IRO OR MOJ. Good damage. I have an Iro; Very good damage but low armor. Moj; Very good damage and good armor AND rather decent health. Maybe Torikaze too. The dark forests (Left, Left then a little lower, Bottom Right) are filled with all types of Osanai. Ones that hit you with circles, wind, green stuff, fire, but not water. The middle forest contains a lot of normal attack Osanai and fire ones, and a few green stuff ones. Here AND the deserts, you will find an Osanai called Megane. For some reason, it does infinite damage. Maybe it's a hit or miss kind of thing. Try to kill it and see what it does! The ponds (Directly to the left of the top house of the shops, Right under the middle forest) contain water Osanai. I hate them. They suck. The field (Right above the middle forest) has fire Osanai, rabbit ninjas, and polar bears. AND MEGANE. The deserts (Right of the shops, Under the bottom pond, Right of the middle forest) have circle shooting Osanai, normal ones, and fire.
Most of all of the fire Osanai are strong. Especially the one that looks like ponyta. Water ones are pretty weak but have good health and armor. Circle ones... lots of health. Green ones, balanced. Wind ones, if they have strong winds they're good. Real good.
Pro tips: Just because they are really rare doesn't mean they're good. Like the Kitsunekaji. It fails.
Good damage > Good armor + Good health
Grind til you can't grind anymore.
Never get health and/or armor based Osanai. NEVER. After lvl 20 battles become damage based.
Have fun! I guess.
