You are a small ship, trying to survive the hordes of enemies coming towards you at every moment. Every move counts. Press the arrow keys to move. There aren't any more mechanics, except sliding. If you only press one key, you slide, and that could potentally be detrimental. If you want to avoid sliding, you should press a key right after the one you pressed. It might lead to some difficulty controlling the ship however..
Some things may be buggy, so watch out. There may be more mechanics implemented in the future, but for now the only thing you can do is dodge enemies coming right at you. V1.0.0: Nothing much. Only 3 waves and 3 enemy types are available.(Most of the time was spent testing rather than developing.) Wave save feature is also implemented. V1.1.0: Wave 4 and 5 added. First boss is available. Beware, it's hard!
