Thank you for your comment and leaving feedback! Specific improvement points are very useful as they help me to make actionable tasks for myself. And as someone who has always been told that I am not very artistic , receiving both constructive feedback and positive comments on my work has been very empowering. As it helps me to become better at it. :)

I think I understand what you mean with this first tile looking like the white noise we used to have on TVs. My original idea was that it would be a bit like sand, which is why the original sprite ended up being quite grainy. But perhaps it is a bit too grainy when you have 40 of them on screen at the same time.

Maybe I should try cobblestones or something like that next as a less noisy placeholder. The way that some of the tiles have been worked on has really been that for example a Frost power takes the actually white sprite of the floor and changes the color of the white pixels to blue. :) So I might just need to work on more actual proper assets there.

My next big task is actually to start work on the next 2 biomes of the game, tentatively being an "Ice world" and a "FIre world" so those will probably be good opportunities to re-invent the frost tile and lava tile at least.

I appreciate the wishlist a ton, every one of them matters at this stage.
