I use Scratch, mostly TurboWarp. and I'm very worried, that putting the future projects on this website would result

with a same ol' three stars. (Not poor games but just fine, not very good and not perfect games.)

The game engine used doesn't really make too big a difference to the score, since people aren't judging the tech behind the game, but rather how the gameplay, art and music come together in the finished product. Of course, you may be able to get visually better effects with certain engines than others, or some may allow you greater flexibility (which would show up in the game) but for the same game, the engine doesn't make too much of a difference.

Sure, there may be some people who just vote low scores for anything made in e.g. Scratch or RPG maker but they're in the tiny minority - they're not going to sway the vote a lot.

being honest one of the flaws of the judging system on newgrounds. there are people that will just judge it because it is a scratch project thinking an 8 yr made it when really when you upload a scratch project to newgrounds you don't have to follow scratch's shitty rules. Litterally you can get your project taken down from scratch just for containing FNAF in it like wtf. If FNAF is not allowed then why the hell is johnny sins on scratch.

newgrounds should be a good place for scratch projects to be acceptable since you can actually make some really cool things with scratch that can impress people but no there are people that downright vote the project just because it is a scratch project.

scratch is kind of hard to run but i don't think it effects the rating

“Engine bias” sucks sometimes but as long as ya make something cool people mostly won’t mind, as they should. Scratch is cool! I used it for many many years.

You will break free of the three star rating, I believe in youuuuu!

well i mean scratch can import svgs so and flash games use that and you can rip them and use them in scratch

People don't rate based on engine, (usually), but Scratch is a rather limited program, easily prone to bugs and graphical issues.

It's possible in theory for a five stars worthy game to be made in Scratch, but it's not likely, and it'd probably be better to use a more robust engine from the start rather than forcing an educational game to do things it simply isn't designed to do.

However, the content of the games is more important overall.

Even with a better engine, if the game runs poorly, looks bad, or suffers from glitches or design issues, it's not gonna get good ratings.

From the looks of it, your visuals are actually pretty ok in Horau, but it seems that of the three games have had some issues with programming and gameplay.

Since this is the "weakpoint" of your projects, focus should be put on improving your programming skills.

It may also help to take your time to test and play through your projects a couple times before uploading, so you can try and catch some of the issues before release rather than after.

A focus on quality rather than quantity may also help.

It's better to put out one good finished project than to rush three smaller ones into existence.

The wave motion thing seems fine, but should be put into "gadgets-other"rather than "skill-avoid", as it is an AI demonstration where no avoid gameplay is actually available.

(This may also improve its rating slightly by reducing the potential of disappointment from people expecting an actual game.)

Overall, try to work on the gameplay portion of your games.

Whether in Scratch or any other program, that is the most important part of any game project to get right.
