Response to comments
Hey, everyone who commented on my entry! Thanks so much for playing and commenting!
I felt it would be good to respond, so here’s some quick answers to the comments.
(1) Sorry, I was too busy making fancy-looking graphics to do the reset button ><
(2) Sorry, I couldn’t finish the music in time, so there’s no sound! Once I regain some energy I will release a new version with sound. I think this game has legs.
(3) Yeah, the wall-switching is a bit cumbersome. I guess this is where memorization comes in – if you know the pattern beforehand or can read it quickly, then you know which wall colours to use and can set it up pretty quick. Not sure if that’s bad design… You can actually just hold down a shot button and move laterally across the wall to change all the circles at once, by the way.
(4) Sorry, there wasn’t a help screen, or it would be more obvious that there are three weapons (Z, X, and Z+X), and that each corresponds to a different colour for wall-switching. Edit: I haven’t encountered any problems with the wall-switching – maybe my explanation was unclear? An animated tutorial might help.
(5) shrt, it seems you have one of Those Keyboards. I’m not sure what the exact reason is, but some keyboards (like the one on a laptop I once used) seem to not want to register a combination of a letter and certain arrow keys at the same time. So you can’t press Z, Down and Left together. Best I can do is to put in 360 pad support, and possibly other pad support too, in the remake.
(6) All told, if you actually use all the bombs, you have 12 shots of the superweapon. This is (in theory) enough to clear the Horrible Rush Of Enemies before the boss, and kill the boss, without firing a single conventional shot, and being invincible about 90% of the time. (Edit: Assuming you don’t die before the Horrible Enemy Rush, that is.) C launches the superweapon when your wall is up, and re-summons the wall when it is offline. I was actually worried that it would be a game-breaker, but it seems it… well, wasn’t. If you’re having trouble, use more superweapon!
(7) There’s a semi-hidden trick to the game. You can operate either the spread shots or the laser simultaneously with the missiles. To do so, hold either the Z or the X key to fire the spread or laser, and simultaneously tap the other key (X or Z). This increases your firepower very substantially, but also makes your movement speed erratic, so threading a path through bullets gets a bit tougher.
(8) Have you ever encountered flying monks that *weren’t* attacking you? 
Edit: (9) Muku, your comments were completely spot-on. I wonder if you were reading my mind! Yes, I realized a couple of days ago that I should have added a readme with instructions – will try to remember to do so next time. Yes, I am actually considering a more extensive remake/expanded edition with SNES-style blocky sprites (after I finish solving the more obvious issues). Yes, I did think about adding one or two ticks of acceleration, but my experience in the past has been that adding excessive acceleration to a shmup causes the player’s movement to feel sluggish – that’s probably something that can be solved with tuning though, so if I do a more extensive remake I will seriously consider it (thanks to your feedback!). Finally, the wall mechanic currently relies heavily on memorization (you switch the wall between waves to prepare for the upcoming wave); in the remake I am thinking of giving the player the choice of 2 different “wall modes” – manual and semi-automatic – where the former is the same as the current wall, and the latter is easier and more responsive but also far less flexible.
