Incidentally, Touhou Kouhentan ~Accident Outside Wall~ is an absolutely crap game. Remilia starts off with no ability to attack opponents under her, and you get knocked-backed significantly if you get hit. To get additional skills (or upgrades like double-jump), you need XP, which you get by defeating enemies. (there are some one-time xp powerups, but this is largely moot since you need to at least be able to double-jump to get to them). Defeated enemies generally grant double digit XP. All upgrades require at least 1000 XP, with further upgrades costing more. Some skills have prerequisites, with most of the prerequisite skills (yes, plural) needing to be at level 2~4 before you can even get them.
So yeah, the game expects you to grind enemies to get XP. You kill enemies, wait for them to respawn (or restart the stage), and then kill them again. Which is a big pain in the rear end to do with Remilia's initial shitty abilities. And it is nearly impossible to hit enemies under you without getting hit several times in the process. And this game absolutely loves throwing pits and downward stairs at you.
Did I mention that this game is a platformer, without a jump attack? (landing on top of an enemy hurts you instead AND knocks you back a lot, so the temporary invincibility isn't that useful) If I want to grind in a platformer I'll play Maple Story instead. (and that game isn't all that good either.)
Bosses do give a nice chunk of XP, but fat chance of getting to them with Remilia's initial loadout. Expect to grab a few upgrades before you can even reach them.
Skills and magic require directional button inputs (like a fighting game) to work, which is arguably the best part of the game... except that the engine is wonky and sometimes doesn't know which direction you're facing. (thereby messing up the button inputs).
It can be enjoyable if you memory-hack the game to get enough XP for the skills you want (which I did, I'm not going to grind.). The game is rather short though, and all bosses can be killed by spamming Spear the Gungnir 2~3 times. (and no, I didn't give myself MAX skills either) Stages are short, though fiendishly hard if you don't have enough upgrades. Stages are also completely linear, with alternate paths leading only to power-ups. (except the one on Youmu's stage which allows you to skip almost all the way to the boss.) There seems to be no bonus content either. (unless you count Sanae and Suwako stages, but they are more like Megaman's later stages which are unlocked after defeating the initial bosses. And is part of the main story instead of post-game content.)
The written dialogue (pre-boss battles and post-defeat) are also sort of...mediocre. (ignore this if you can't read Japanese.)
The whole game can be completed under an hour (took me 30 minutes) if you hack in the xp for the skills. Otherwise, you probably need to spend 5~10 hours to grind for the skills you need. If not more. The game just stinks of Fake Longevity.
It's a nice way to spend 30 minutes by breezing through the stages though. Sort of like a nice flash game if you disregard the required xp grind. 'though with a game clocking in at 600+ megabytes, I expect more.
