there's a lost of computation intensive effects indeed but it does make the game barely playable for lower end computers and also those are effects that enhance whats on your screen, not make it. its like condiment, you need a meal to go with it. dont get me wrong, i think you had correct level visuals but it would have better used finer details, geometry, normals or textures, which in the end would have costed as much if not less performance. its like a plate of pasta with the finest salt, yes, it does taste better than pasta without salt but it could also taste better for a more affordable price with regular tomato and cheese (not a cooking expert tho dont mind me ^^')

also invisible walls as a main mechanic isnt viable unless there's a hint. i nearly left the game at spawn because the entry toward the maze was a fake wall (and its especially more important for non pros games as players wont have faith in the dev that the game is playable)

beside that, nice distortion effect and voice acting. also i suspect the maze is randomly generated too?

I agree with the previous commenter, that there needs to be sound clues near the crystals and passages. Also some indication of how much time I have left and how many crystals left on the map. I did see the distortion effects, but they triggered too close to the walls to be useful enough. Also running speed was too slow.  The options menu didn't work (tried accessing it from the game).As this gamejam showed, it's not easy to make a good maze that players will enjoy navigating. The graphics are nice, and voice acting is a nice touch.  

Okay first of all, gameplay wise, I think this is fine. I can get behind a good maze game as much as anyone. However, I do have some personal reservations about not giving the player any real way to detect invisible walls -  outside of doing what effectively becomes wall surfing to find all hidden paths. 

As a mechanic? I think invisible walls are totally fine, and can work really well - I just don't really want to wall crawl the entire game to make sure I don't miss something. A hint like a subtle crack, or a glyph, or even a soft directional noise que can go a long way in helping the player out while still keeping it interesting. 

As far as presentation, the game is quite pretty. Lots of nice techniques used here to give the game a polished look. And the voice over? Is that proper voiceover from someone? You love to see it. 

I will say, I have a relatively mid end graphics card, so I wasn't expecting a perfect 60fps, but believe me when I say that this game suffers some pretty substantial performance issues - particularly when you look directly at the center of the map - which is where I think most of the particle effects are concentrated. 

Good game! I enjoyed it - even though I failed to find all the crystals. 

AAAA this game runs at 2fps in my pc, wished the was a graphics option so I could properly test this game (played for like 4min and I got worried my processor might be as hot as the surface of the sun, being an old amd processor and all), didn't expect you implemented all those cool visual effects considering the presentation.
Anyways, I wish you to continue learning and keep having fun making games!
