Thanks for the feedback folks, I'm glad you enjoyed it. :)
@zgragselus - Thanks for the feedback. Yeah, I'd like to add some more water effects and more variety to the textures. I was planning to create a custom blend shader that would add a sediment texture where the normals are pointing up, and maybe some different rock layers based on world space depth.
I'm not sure how the counter could break, did you realise that you have to return the samples to the starting area to score points? I'm sorry the tutorial texts moves out of screen too quickly, I literally threw it into the game at the last minute.
There isn't an end game atm. I'm not sure what it could be, maybe I could add some special samples you have to hunt down to complete the game (fish or something?)
@crass-sandwich - Thanks for the feedback, I totally agree, even I get lost! It really needs something like a minimap or maybe a compass to guide you back.
@sir-daniev - Thanks for the feedback. Yeah, it would be pretty easy to add some particle effects for the turbine and it would really help to sell the movement. I'd also like to add some layers of marine snow and maybe some sediment to kick up when you move close to a surface. A depth gauge would be a nice touch too, I'd not thought of it.
@futil - Thanks for the feedback. I probably spent too much time getting the robot movement right, but I'm pretty pleased with the way it turned out, and it's given me some ideas for another game I'm planning. Yeah, I had plans to add a bit more life to the caves but didn't have time in the end.
@davideperozzi - Thanks, I'm glad you liked it! :)
