This is a pretty decent release. (Metalcore? Hardcore sounds like Metalcore to me. So sorry...)
The only thing I would critique you for is the fluctuations in volume. Some parts of the track sound overcompressed, to the detriment of the entire soundscape. Example: Track 1 at 0:11, right when the guitars come in, and sometimes else during the EP.
Other than that issue, I like what I hear. The drums sound dirty and garagey, guitars are well played, and some of those High Pass Filter transitions work very well indeed. Your lyrics are good, the vocals are well executed, although sometimes they sound a little bit young (?)
There's a good bit of energy going on here, and I don't have any problems believing in you, which is a must for this kind of music.
All in all a good release. I'm personally not going to get the EP, but I know of several who would like to, so I'll repost the link and send some listeners your way ^^
