Hi! thanks A LOT for uploading the web version.
So... the idea is unique. I like unique. But the clicking on the banners is too fiddly and more annoying than fun, like they move a lot, the clicks don't register correctly sometimes, you should be a little more generous with your hitboxes (at least a few pixels). This is a common mistake and here's an why you should be generous with the player.
Also, sometimes you can't really see the powerups coming, they are too small and don't make good contrast with the background so while you're focused on clicking the ads you can't really see with your periferals that a powerup just passed by.
With the speed the game is asking of you to close the banners it's hard to react to bomb banners, you just see red crosses and try to close them as soon as you can, you don't have time to read the contents of the banners before another ad just pops right in front of the one you were reading. So every time I clicked a bomb banner I was like "oh cmon, seriously?".
Or maybe it's just me, maybe it's a skill issue, maybe I'm not the target audience to these fast reaction click games, so it would be unfair for me to rate your game because maybe it's made for another audience, it's just not my cup of tea, sorry, but I'm not giving it a bad rating because of that.
The idea is not bad per se, the problem IMO is the execution. Maybe the powerups could appear for a second like the cookie clicker's golden cookie instead of being a skillcheck at the bottom of the screen.
Still, don't worry too much, that's what game jams are for, to try and to be creative. You got a unique idea and you executed it, that's more than what a lot of people can achieve, at least you didn't make a puzzle platformer like most people do in jams, so that means you're a creative person. I hope the feedback helps. Keep it up!
