Loved this game when i first saw it on the GMTK game jam! i like how you have used shadows to fit the theme of 'built to scale' something that didn't occur to me but a clever and interesting way of applying the theme!
It is a very addicting and fast game! i always went back to try and beat my high score everytime i failed. It can be suprisingly tricky to keep track of both the background and the obstacles on the floor :)
only visual tweak i could think of could be to maybe make the gecko's shadow be more connected to the gecko? adding some spotlight type lights could make the scene feel a little less bright too?
amazing game overall and a unique take on an original classic.
