As someone who has done speedruns of crystal seeker, its really cool that the game was designed with speedrunning in mind. I was actually the first person to "discover" the axe climbing at 17:00, so it was crazy to see it was intended all along. It was really fun to run the game, I should really go back to it sometime, maybe try to get the Any% record

The person who said this is not impressive doesn't know what they are talking about. This "generic platformer" is better than anything I could make in my 2 years of using unity because like you said it has a soul. In my opinion you have something truly special here. Hats off to you 👑

[Kiwipai]

Imagine calling something "meh" because what a single person did isn't more impressive than Unity, a program that has been developing for almost twenty years by hundreds of employees.

[oglothenerd]

Bruh, you made an entire graphics engine, and then created a game on top of it! This is super impressive! And the fact you made it in scratch, means you probably had to optimize the heck out of it! I am super impressed! Well done dude! I personally don't normally watch ScratchTubers, but you are an exeption! I subscribed, and turned on the bell! And left a like! I want to see more content! Keep it up man!

[MethDealer]

When griffpatch says "wow", you've done something amazing.

Saying that this is just as impresive as making a 3D engine in C++ is like saying that athleths running is just as impresive as driving a car.

[sierragutenberg]

I still remember when I first played this 2 years ago and wondered how the hell it's so smooth IN SCRATCH

[marcomoscoso]

Your game has a cool retro vibe to it and the level design is fun, setting aside the limitations. I remember that the games/prototypes I feel most proud of, are the ones that are not as graphically impressive but the ones in which I learned more and had to do more hard work coding.

[UltimatePerfection]

You should consider making an expanded version with a real 3d engine such as Godot, because this kind of lovely retro game is something I'd pay for on Steam.

whoever voiced PratixYT needs to go to hollywood, the accent, the deep voice, the menacing tone, everything is just immaculate. i guess the rest of the video is cool too.

[thatdudewiththeplant]

I had never heard of this game before watching this, and my previous experiences with '3d' scratch weren't very impressive, so i went into this video thinking this was just another half baked 3d platformer game, but no. You dominated all competition. I was genuinely blown away when i saw some gameplay of this. Good job mate

[jademonass]

as someone who coded a 3d rendering "engine" in pygame i cant imagine the effort to make this from scratch

[alessTheDev]

I can't imagine what this man can do with an actual 3D game engine

[JotaleaGG]

This remembers me to Spu7nix, who made a whole physics engine in Geometry Dash just to make a level. Congrats btw

[eboatwright_]

This game is legendary! This is the kind of stuff I could only dream of doing in Scratch back in the day haha

[RKIOrbMage]

I still can't believe this yt channel exists, you're like... my idol. Crystal seeker is one of the best online games I have ever played, The fact that it exists is actually mind-blowing. For the sequel, I wonder if you could find a way to make 3d enemies without affecting performance.
I cannot wait for you to talk about the tower defence!

[CRMSN.]

Been watching all your videos, really like the quality of the videos, you put in so much effort and there’s so much quality! Love it!

[LNPV]

This video was the best scratch video I have ever watched. I liked the game because it had the n64/ps1 atmosphere.

[maxwellbeals]

This is amazing. Probably the coolest project on scratch. I had in fact played the game before, but I didn't know it was yours. Good work.

[McTonk]

I just played it and all I have to say is "Wow" and "How is it widescreen"
