That was very fun! I always love it when people add some kind of secondary game on top of the base clicker game, it makes it so much more fun. There are somethings I want to mention & ask for clarifications.
The first is that I think the button to attack and defense should either be larger or assigned to different buttons. I've missed clicked a few times and not being able to defend/attack because you didn't click the thin horizontal button feels bad. having a button that's easier to hit would make fighting the guards much less frustrating.
The second is that I think the step counter's number display need to be fixed. I was able to get up to 117 steps and instead of showing the number it show something like this:
11
7
It's purely visual so it doesn't impact gameplay, but it definitely break the immersion a bit.
The last part is that... could you explain what the numbers mean on the computer when you collect the stuff? I don't get what it supposed to be. at first I thought maybe it's multiplication, but the reward that I got seem to small for that. some kind of explanation, maybe a sticky note or something placed on the frame of the computer would help.
I would love to see how many levels this game will have and what explorable places I could go to, maybe even puzzles that needs to be solved to get to the elevator? I could see a lot of things working for the exploration so I would love to be able to play a full version of this game :)
