Maybe it's just me but I'm just unable to use designs and bookmarks without having to go to the designs section quite often.
So when I press D to get to the designs section while I'm building something, having to click on Back to game feels a bit disruptive. Pressing D again to get back to wherever I was would be so nice.
A nice change from the food games :)
However I find that management of bookmarked weapon parts is rather awkward. Between the parts I want to use today for a sword, those I want to use today for an axe, those I'd like to buy today, those I'd like to save for later because I nearly have all parts for a design and the rest, one bookmark just isn't enough and not getting it wrong requires a lot of visits to the designs page.
It would also be nice if the designs page showed a reminder of today's foes, when used during the day, just like the shop does, so one can select the best candidate designs.
Nice game.
A big improvement would be an upgrade to the horizontal speed. Quite often I miss targets or hit red shapes because the slow lateral movement doesn't allow to react in time.
