Hi Graham, looks real nice. That start up animation when restarting is cool but it feels a bit awkward that you have to hit retry, wait for animation to finish, and then press start. A quick start back into the action is always nice.
-When the screen moves up sometimes it clips through the roof.
-I am never looking at the UI so I did not notice what certain power ups were for but an idea would be to have each gear, when collected, move to the top right where the gear icon is and when you have x2 it shows two gears going up.
-at one point the high wall where you slide under obscured my view of the object you have to hit and it can feel like a cheap way to punish the player if they can't see it coming.
-every so often when I hit continue I immediately hit the object right after the one I hit. You could set a range around the player that clears the closest obstacles giving us a chance to get ready.
- I like the dynamic camera movement when going in and out of tunnels, up and down. When it goes back down we lose the avatar for a brief moment which might be critical for these type of games to never lose the avatar.
I like the Magnet power up and the effect it gives, and the shield power up and how it takes down walls if you hit it, I hope you come up with a diverse group of fun power ups that play with the robot theme.
Also it is always nice to have a background or purpose for gathering all these gears in a dangerous situation. Even if some people don't care about these things for some people it does!
Ruh Roh, I spilled all the gears along the sewer line and if I don't pick them up as fast as I can Dr. Robotdroid is going to repurpose me into a vacuum cleaner! AND the deadline for the annual Kill all humans science fair is tonight!
