A lot of side-scrollers, platformers, retro-looking games claim to be "old-school" and play like the good 'ol games from the NES era. - They all lie.
Games like Blood of The Werewolf, Super Meatboy etc etc...they are all good games but they don't feel nor play like NES games.
Just because you have a 2D side-scroller that is super hard doesn't mean that it's "old-school".
But here comes Oniken. I was sure that it's another one of those pixelated games that is super hard, claims to be "old-school" but doesn't feel or play like an NES classic and once again poor old Mets would be dissapointed.
I still gave it a shot and WOW! Just WOW!
Oniken feels just like it came out from the 80's!
The combat is smooth - Your main weapon is a sword (that looks like a katana) and you can throw grenades as a secondary weapon. Grenades are pick-ups tho and you can run out of them. You can also find secret 1-UPs and some sword power-ups if you get lucky.
After each level you get rewarded with a cutscene that looks like from Ninja Gaiden...which is nice. Don't be afraid tho, the game is not as hard as Ninja Gaiden. It's challenging, sure, but it's not hard.
I managed to finish the entire game in 5h...it's possible to speedrun through the game in 15-30 minutes tho.
There are 6 stages and each stage takes you about 2-5 minutes...that is if you know what to expect and you're familiar with the level layout. The first playthrough will take some time. I especially hate level 4 which took me the longest amount of time to beat.
If you're looking for a throwback then this is it. Look no further! Buy Oniken!
