Interesting Concept but falls a little short.
The game has an interesting premise, controlling two characters simultaneously in order to complete a series of puzzles. On the positive side the game has a nice arcade feel, reminiscent of very early arcade titles; in addition the idea of forcing players to control two characters simultaneously was a refreshing challenge and makes coordinating otherwise simple puzzles a bit more difficult. The control is the games biggest selling point: forcing the player to use both right and left hands (and thus right and left hemispheres of the brain) in a effort to navigate the traps and achieve a high score adds an unexpected level of challenge that makes this title stand out from others.
However the game does bring its fair share of faults, as others have mentioned there were some collision problems, but the game's premise of two characters simultaneously, while it is the game's greatest strength it is also the greatest weakness. While not standard, when using two hands I would have appreciated the ability to map the controls to other keys, that way players could keep both hands on the same row of keys to make ambidextrous controls more fluid. I feel that this game would benefit greatly by allowing nonstandard control options.
Overall this is a great game in theory, but falls somewhat short in execution; lacking an certain polish that would have made this game into something great. Excellent effort and I look forward to seeing how the premise is expanded on and polished in future releases.
