Very cool! similar to Castlevania. I had a hard time trying to climb using the pilars... hahaha. Authough I still have some points that you could have worked a little bit... if I may:
1 - Whenever you die, the text at the beggining starts again
2- At the begining, when the text is still apearing and the scene is totally black, you still able to use the comands (mouse and keyboard) and the sound of it is reproduced, authough we are not playing it yet.
3 - Some skeletons seems off, I mean: some of them can be reached by the attack, but sometimes their hitbox seems to be offset or something. The swords does not seems to cause any damage sometimes,
