Very funny game.
The physics and upgrades are super fun, and the look of the player and enemies adds a lot of grotesque charm. The stones that block the sword are a nice touch, and the chunky enemy doing clumsy dashes is the second to last cherry on top. The thing that really stole my heart and added the most fun was the upgrade that makes the ball bounce around the screen. Very creative take on the theme.
The upgrades motivate you to keep playing, and the introduction of new enemies does as well. I just wish the progression was a bit faster. There were moments when I was already getting bored and only then a new enemy appeared. I’d probably introduce all enemies one round earlier.
The visual side is where the game struggles the most. The player and enemies are fine, but the background feels boring and I wish more was happening there. What’s the road in the middle for? I was missing a car driving by that could potentially run you over.
It’s a cool idea that’s definitely worth expanding with new levels, new enemies, and more upgrades, though of course I know game jam time is limited.
One more piece of advice would be about presentation. I’d rework the screenshots, add some text, and try to make them more clickbaity. The idea itself is interesting, but nothing really hints at that on the game page. You don’t feel like clicking at first, but once you do, you’re positively surprised.
Solid work!
