I was able to run it on a different device. Pretty nice gameplay loop with the upgrades feeling impactful but not too powerful. I think the difficulty ramped up a little fast after the first few rounds, but honestly not a bad thing.
Sound design was probably the only issue, where everything was too loud and quick. It’s a jam, so I’m not blaming you for not having volume sliders, but it is something to consider if you want to continue development.
Visuals are fun and clean. Probably the strongest pillar of your game.
Nice job :)
