Got to level 12... I love the simple controls. Very easy to pick up. Difficulty increases are understandable and fair, yet surprising. I like the visual, sound, and music. I am not sure how you'd even expand this though, maybe different enemy types and speeds? Great work
It was great seeing you play live! You almost made it, congrats!
In terms of expansion, I agree that different enemies and speeds would be in. I can also think of other stuff such as a score/combo system, maybe some power-ups, an endless mode...I'm sure with some brainstorming we can come up with many good ideas for expanding the game.
Thanks for playing!
