Thank you!
The corner strategy should stop being viable after some time — as the game progresses enemies get more hp and the laser should be mostly outclasses by bombs for mass kills. Maybe I messed up the balance in the last few moments though.
As for the movement I agree. It was the first thing I made for the game and it ended up being goofy. In the last moments before release I improved the movement a lot anyway. Believe me, it was even worse.
