Why did the 'Operius.exe' got blocked by Windows Defender SmartScreen? 

A very good game though

SmartScreen blocks pretty much everything that's not "trusted", so it's essentially a whitelist. Most other indie games you'd download online would get blocked by it as well.

But i remembered when i play in 1.1.2 it didn't get blocked by SmartScreen

Great game!

Unfortunately I can't figure out how to get past the spiral enemies in sector 6, how to avoid getting hit? The only option I see is using the shield from sector 5.

After many many tries I cleared sector 6 with pure luck. The spiral enemies seem a bit too hard compared to all previous enemies imo.

I noticed in Arcade you can keep scoring in a sector if you miss the last ring. Perhaps it would be better if you stop scoring once you've missed one to prevent milking early sectors for points.

Since it's hard to survive for many sectors in a run starting from sector 1 it be might fun to have a separate leaderboard where you can continue your sector's best score.

I noticed you can easily clear sector 9 by keeping the boss at the top without hitting him.

For the spiral enemies there is a pattern to figure out, it's just a rather confusing one, but that's on purpose. One thing to keep in mind is that they always spawn in front of you, so once you find the safe spot you can abuse it every time.

As for milking early sectors for points, that is intentional. With later sectors the game gets more difficult, but you also earn points much much faster. Not to mention that the score you earn gets multiplied more sectors you cross, which is also kept track of.

Ignoring the sector 9 boss is also intentional. Defeating bosses give you a lot of points and a shield so there is an incentive to defeat them, but if you really want you can just focus on the rings and skip the sector without even defeating them.

Thanks, I'll see if I can figure out the spirals.

The games I usually play always have some kind of countermeasures against milking, that's why to me it seems odd but so be it :)

was this made in game maker studio?

I think it was because of the icon, please correct me if I am wrong.

Yep, it was!


The game is very good. it has simple but stylish graphics. the gameplay is simple but addictive and a lot of fun. the truth is that the game is very worked. Glad you won the opera GX jam.
