nice site, but could you add or switch to list view? grid view is ok in a gamestore or a frontend or some such, but here it just makes it really tough to know what i'm clicking actually, with all these stylised lettering and game names in japanese.
it also seems you're using uncompressed images for your games lists. please use proper thumbnails, because those category pages load very slowly even with a fast connection.
also, the search on your page does not actually search your page. you'll need to add a custom default query for "platformadventure.weebly" to actually show results from your site.
edit: oh yeah, i consider Zelda clones Metroidvanias too. It's obvious with Zelda 2, but even with other Zeldas the only distinguishing factor is that they're tile based, or in 3d. But Metroid Prime was 3d too. so what matters is game mechanics, and Zelda clones share most of these with MVs: powerups, heart containers, secrets, puzzles, killing mobs, monster drops, etc. presentation may be different. but it's still mostly the same genre in my book
