I like it!
Excellent sound design, logical controls with a great tutorial, a bit of writing to make things more interesting, and I enjoy the rhythm mechanic even if my tempo and memory is terrible. Also, bonus points for the ability to pause any time.
The biggest point in your favor though is that the game isn't overly easy. It gets complex pretty quickly, and honestly as a blind gamer, I'd rather lose at a game meant for me because of a skill issue than win easily any day.
Maybe this is unfair to a first time jam entrant, but any game with the word blind, darkness, sight, light ETC in it is just kind of annoying at this point. It's really overused. A game with a blind protagonist is much more annoying to me, but since you didn't do that here, I can hardly complain much.
We've had many of these bopit style press arrow to react games in the past and they are getting a bit old, but again that's hardly something that I can really hold against someone who doesn't know that, and at least your game used rhythm and had a steep difficulty curve which is more than I can say for most others in this genre.
I do wish that the game would penalize you for attacking too soon though (within reason).
If the game ever gets expanded, I hope that things get more complex. Maybe with the enemy countering and needing to be blocked in the middle of a set and you having to figure out where you left off, or adding the down arrow key to block in the middle as well, or making you hold the shift, control, or alt keys with the arrows to block elemental attacks from a wizard, putting you on the offensive instead and making them defend, making a hard mode where injuries carry over to the next fight, changing the block and strike sounds for different enemy weapons, letting you use a special attack after building up a meter, having a bard enemy who tries to confuse you with music of a different rhythm ETC.
A game like this is inherently kind of limited in scope do to not having free movement or equipment, but there are a few things you can do to spice it up a little.
Despite any criticisms I may have, this is a solid first time audiogame and I think you have a good chance of placing in the top 5, definitely the top 10 at least.
Thank you very much for lending your time and effort to our jam. It really does mean allot, and I'd love to see you back here again next year!
