Bugs:
(As mentioned in another comment) Main character can avoid the platforms by walking straight-forwards and still win the game. (This makes the platforms lose their purpose)
Strengths:
Art-style is colourful and undetailed which suits the (presumably) toy-like style of the game.
Game includes a sound effect for jumping to make the game more interactive.
Background is detailed and uses darkness and lightness to simulate a 3-dimensional environment.
Weaknesses:
Game is very short and has very few mechanics
Changes or Improvements:
increase the number and height of the platforms, add more parts to the game (there are currently only 2 platforms, maybe make more and/or a mechanic where if the soldier misses a jump and falls down, they have to restart the level)
