I made ooparts 3 because 1 and 2 sucked, and now I made this because o3 didn't age well.

I've been watching gmtk videos, playthrough of modern fangames and such to study level designs and it seems I still have lots of room for improvements, especially for needles.

Also, while I did taken extra stages seriously this time(unlike o3), I'll admit I went a little overboard with the extra boss. Sorry about that.

very good game, i had a lot of fun. some gimmicks are very well use, my personal highlight is level 6, and is not all corridor needle (there are some corridors still) but is a huge progress

some things that not affect my rating: the bosses sprites has to be like milanesas, the bigger the better, okay seriously some bosses like the third one are so small they're cute.

and things that affect my rating: stage 9 could have a better use of the timer triggers, they only activate a spike in front and that's it... there is a lot (okay not a lot, but there are many) odd jumps, random diamonds, random corners at the end of the saves only to make things harder, nd personally i'm not a big big fan of the "do half screen to activate a trigger or collect all keys to unlock a door at the start"


Overall, a big improvement over the other games. There are some parts that are "ugh", but it's a good game.






here is how to get the secrets:

secret 1: screen 1-2... after activate the last trigger, try to jump close to the cherry next to the trigger
secret 2: screen 2-3... do a lap
secret 3: screen 3-2... shoot the random spike top left, next to the camera
secret 4: screen 4-1... in the drop to the warp, keep holding left until you find fake blocks.
secret 5: screen 5-4... do the screen normally, and at the end one trigger top left switches
secret 6: After boss... after defeat the boss, you will find a red dot in the screen, interact pressing UP
secret 7: screen 7-5... collect all the blue skulls
secret 8: screen 8-5... at the start, do the sideways gate
secret 9: screen 9-8... after get the last save, jump down
secret 10: after boss... "watch the credits"

Difficulty exclude extra.

The ex boss ("Game Over" Boss) has been the WORST boss I've EVER played, it's at least 95 difficulty if the battle lasts only 30 sec longer, the RNGs of the second phase are literally TAS-oriented on which you have 90% chance to be completely blocked. This boss is genuinely the destruction of the whole game.

Ooparts IV is a really fun adventure game featuring various simple but fun platforming gimmicks and enjoyable bosses. Hagoe as a maker has a very distinct style that's even after all this time still found in this game, even though it makes it feel dated in some parts it creates a very classic feel to the game.
The platforming is mostly really fun. The gimmicks are used pretty well and there are no major stages that felt unfun, just a few occasional jumps that felt out of place. (The random 9 jump and the breaking block drop for example.)
The bosses are solid. They're generally pretty standard, featuring mostly simple barrage-like attacks. I do feel the hard part was usually at the end and with some of the bosses being a bit slow paced it was teetering at the edge of being annoying sometimes.
Overall this is a great classic feeling adventure game by a maker who really refined their style, while still feeling very "Ooparts". Can recommend.

I've been through all that crap only to get an unwinnable boss.
Sans Undertale reference does NOT help anything.


Jokes aside, this is a pretty big improvement over OOPARTS 3, but it does still suffer from similar issues. This game is a lot less rough around the edges and overall a pretty good time, but it's not the most memorable game. The final boss dialogue was really funny though.
