In general, it's good fun. But, interface-wise, it still needs consideration.
Too many features are grouped into touches and hard clicks on the same controller, and it's easy to do the wrong thing. This seems like it's done for programming ease rather than going the correct route of creating more menus (like Kingspray), or making better use of the fact that it uses both controllers and one only uses the trigger (for spraying).
I always like to know what's wrong first, so "Cons" then "Pros":
Cons
1) It's too easy to accidentally change the resolution of the image when you go to click "Undo", which loses your work.
2) Changing resolution starts you from scratch rather than scaling your work to match.
3) You only have 6 save slots (2 per map)
4) You have a huge wall to paint on, but there's no way of ever painting the top part, so why have it? Are you going to put ladders in your living room to reach the top of the virtual wall? Maybe allow teleporting up?
5) Too easy to accidentally lose your current colour settings by touching the ink dropper with your thumb
6) You use both controllers, but the touchpad on the spray hand does nothing, yet the off-hand is over crowded with options causing the above accidental clicks/touches
7) Black paint won't spray on the subway car's windows - even though it's a different lustre (paint is matte, the windows are slightly shiny) so you can't see your layout unless you first paint in a different colour, or go over when doing your outline/highlight in another colour
8) Could do with a paintbrush option to paint large single colour backgrounds, rather than spend ages colouring in the wall when you want a single colour base to work on - which is made more frustrating when you accidentally lose it by clicking the rescale button instead of undo.
9) Remember to teleport away from the wall before you snapshot, otherwise the camera captures you opening the menu as part of the snap
10) Snapshots would be better if you could take them from the angle you're standing at, or somehow position the secondary camera
11) No open/save dialogs. I realise that Unity is pretty pants for standard VR dialogs, so you have to make these from scratch (as I am with my apps), but I like to choose where to put my saves (usually on my external drive so they're technically already backed up).
12) Would be good to have a help option if you forget the keys. The explanation is in the map selection area and felt like a lot to remember on my first go.
13) Setting it to the highest resolution (snaps just don't look as good as they do in VR if you export in lower resolutions...I found out the hard way...:( ) has very poor performance. The screen rotated, stuttered when I started to spray, frame rate went through the floor. If I had an old spec I would understand.
14) Just noticed that it keeps changing one of my active colour to brown/red randomly (perhaps sampling the wall colour). Luckily, one level of undo was enough to correct the problem
15) A single level of undo... I can't think of an app that has only 1 level of undo? I imagine it's something to do with storing a previous copy of the entire image and replacing when you undo, rather than transparent layers/each spray being an overlayed object or similar/other method.
Pros
1) I feel like I'm spraying a wall. You can spray up close and pull away.
2) Quick learning curve
3) Can rattle is a nice touch
4) Cheap-ish (£2.99 feels more the correct price point)
5) The developer is fairly involved with the community and takes comments on board (comments on Steam, YouTube, etc.)
6) Not immediately obvious, to me, but you can see the colour you've picked by looking at the top of the spray can
7) No paint fumes. :D
It's nowhere near as complex or as polished as Kingspray already is (and it's not even on general release yet), but it has been a (mostly) fun introduction to VR spray painting.
In general, it feels like it didn't take long to put it together, something done in someone's spare time. Accidentally losing work has been a frustrating experience, but I'm glad this exists.
I will be buying Kingspray when it's released on Steam, though. It even has dripping paint. :)
