Cuphead

This free online game focuses on the achievements of a creature, who looks like a 10-15 year old boy who has a cup instead of his head (hence the name of the game). You have to meet the objectives of the level to pass it. Most of the objectives are to collect coins without getting killed by spikes or other obstacles on the playing field. By doing so, you can run and jump up/down. But be careful: it is not always easy to control his actions, since he is always running nonstop (you only control his jumping activities). Also, in this free online game, you cannot control its direction of movement - the hero only changes it after encountering some obstacle (wall). Therefore, a single type of control performed at the right time is of crucial importance to be successful.
