Great submission! It's really cool how much content there is here after just one weekend.
Design [5/5]: Nice job here. The levels are interesting and engaging, the combat works as expected, and the variety of weapons (and the fact that each weapon can only be used once) makes the game engaging and interesting. The fact that there are so many rooms to explore gives the place an air of mystery. I'm always curious to see what's in the next room, which means you did something right.
Adherence to the Theme [5/5]: Yes, it's interesting that you and all enemies have only one health, but there are plenty of other games that have done that before. I think the most interesting thing about your game is that weapons can only be used once. I wish that the game had focused more on that aspect of things, as I've never seen that sort of mechanic in a game before.
Originality [3/5]: Unfortunately, I think this is where the game is weakest. The fact that all weapons can only be used once is very unique and interesting and leads to some dynamic gameplay. Having said that, everything else is stuff I've seen before. The combat works for what it is, but it's not bringing anything new to the table. Exploring rooms and getting to know the layout of the dungeon is cool, but Zelda also exists.
Other Feedback: The footstep sound effect is horrible. It almost blew out my speakers.
Overall, I think this game has a lot of potential, but maybe not where the developer(s) intended. I think the idea of being able to use each weapon only once is a very interesting mechanic that I wish you had explored more. Interesting gameplay is all about having lots of decisions: In Mario, do you jump now, or after running a few more steps? In Pokemon, Do you use a health potion on your Pokemon now, or try to go for the kill now? In Dark Souls, Do you rest at the bonfire in dark souls and respawn all the enemies, or try to make it to the boss and risk all your souls?
These are the sorts of decisions that make games interesting and fun to play, and I think your game is ripe with potential in that respect. Do I pick up the bomb, or the sword? Do I use my arrow on this skeleton, or should I hold on to it until I find a knight? I hope you continue to work on this game, and I hope you take the interesting decisions that being able to use each weapon only once brings to the table into consideration when designing in the future. Keep up the great work!
