The base idea is lovely here, I enjoyed digging around and finding stuff, but I did have troubles with a couple of things. The main one is the camera, for a game that revolves around going up and down, the camera is way to “jerky” for movement, meaning it jumps quite harshly to follow the player, causing motion sickness. A lerped camera would be so much better for this. This is also just amplyfied once you have the other robot randomly digging around under you!
The kid looking in from time to time is a neat idea, could last a little less though!
Graphically the game is spotless, very nice representation!
MSX and SFX are well made, though a bit too loud.
Overally cool idea, nice execution, needs a little fine tuning here and there!
