Damn, couldn't beat your score but got to 321... is that any good😊?
For your first game, this is certainly well done. It was simple, but fun to try to progress further and score more points each time. The power-ups were also enjoyable, though perhaps not too strange but the theme is checked! Graphically, it's solid pixel art, and the 8-bit soundtrack complemented it well. The controls were good because they were super simple with just the space bar, yet it was still challenging to navigate the level successfully.
For future expansion, perhaps more variety, more enemies and even more power-ups with crazy effects could be added. Smoothing the rough edges of the game.
But all in all, a good start with your first game! Keep up the good work.💪
