Here my feedback (Im sorry for my bad english):
-Game Design:
- The levels are good designed.
- It was sometimes hard to get the junk.
-level 2 was a lot harder than level 3 (in my opinion), so they could be swapped
-Sometimes there was a invisible wall I crashed in or my hitbox seemed a lot bigger than my vehicle
- when I moved at the beginning of level 2 down I just stopped moving
-the falling rocks in level 3 wasnt really challenging for me (maybe increase the numer of rocks or their size)
-Fun:
For me it was fun to play because it was challenging to concentrate on the junk and the vehicle. (but it was annoying if I crashed into an invisible wall)
-Innovation:
I think it the concept with the mass and junk is really innovative.
-Theme:
In my opinion it doesnt fit the theme perfectly. The junk and you arent like toghether because it is junk but it fits in the way that you are stronger with it.
Graphics and Audio:
The grphics are mostly nice. The water is very pretty. The Audio wasnt the best but its sufficient.
All in all its a good and fun game except for a few things.
