Nothing specific regarding mobile but we worked on rendering optimizations quite a bit to make the experience smooth. Most notably the render pipeline is based on MRT (Multiple Render Targets) which renders multiple frames at the same time, which is great when doing post-processing stuff. Also we made sure to keep the number of draw calls quite low by merging static objects. There is also a lot of culling going on, hiding rooms that are not visible.
We'll probably post more technical details on X in the coming days/weeks, be sure to follow us if you're interested.
Unity is not quite ready for the web yet, they have a WebGL exporter but it doesn't support mobile.
Finding the right difficulty level was challenging. People have given us different feedback depending on their skill: some keep dying around level 6, some find the game too easy. We tried to keep it difficult enough for it to be still being joyable by everyone. I agree personally that it should be tougher (and with more levels)!
Same thing for the "tutorial" aspect of the first levels. We wanted to make sure that casual players would not get overwhelmed too quickly.
About the tier 1 bow, you don't have to buy it first. Apart from the sword, you can buy weapons in the order you choose.
The shop was put as a incentive for people to keep playing in the context of a Web game which you don't know anything about. We feared players would not understand the scope of the game without it. I tend to agree with you though, as a gamer I prefer exploring and finding hidden items.
