Sineonara

You control a sine wave. Adjust its amplitude and frequency and balancing the charge required for each attack to prevent waves of shapes from reaching the left side of the screen.

There is no end goal; just try and hold out for as long as possible. You regain some health at the start of each wave.

My (riSygneD's) submission for Game Off 2025. I only found out about this about a week or so before the deadline and figured it would be fun, and I was right! My best is reaching Total 110, though I don't doubt I could do better with more time :)
