Fun little game, liked the retro graphics and swear those objects were things from Atari games... probably just dismembering to fit the blocky graphics.
The controls were a little strange at first and felt a little unresponsive - sometimes clicking the keyboard would work somethings needed to hold down the key.
High score reached was 251 and probably could beat it - agree with others on ramping up the difficulty earlier would help and prevent the hide on the side shift only when needed strategy.
But overall nice submission - keep it up
