Fun game! The gameplay loop is quite addictive, with a very good polish on the juice :)

It’s nice you managed to give it an ending. As you wrote, there could be a bit of balancing if you wanted to make a longer game, but for a jam it is perfect!

Great submission, this looks great and plays really polished! I did a have a few issues. One is the freeze someone else mentioned earlier happened to me a few times and another is that you can hit continue while in the menu to upgrade a bullet and you play the next round with the "Apply effect to:" overlay on screen. I'm a sucker for the pixelated style and it is well done here and the music fits it great. Sadly I wasn't able to get that far because the few times I had a good run the game froze, I had a run where I had the replayer upgrade twice after the 3th upgrade shop and was about to go crazy but then it froze a few rounds after. I wish I didn't have that issue but can't put it against you and if you are planning on fixing post jam I'd be down to help find the issue if you can't recreate it.

This is the most polished game I played so far! Really impressive stuff, awesome work!!!

I did encounter once when the game froze (could of been smth on my end, I'm not sure?) But this game is so well made I can easily put that aside!

This is really polished and well made especially for a game made in four days. The effects and visuals are really satisfying. This also kind of reminds me of noita, and I wish the reload deck upgrade could be applied to a certain card so that it reloads the cards to the left of that card, so that you could make a powerful setup in the first few cards and then reload it to double it up, although that might be too op. I also wish that the upgrades menu popped up immediately instead of pausing the game for a second and then popping up.

That's a great idea. The game looks and sounds great, it was very fun to play and was very polished for a jam game.
I agree with other people that the upgrades were interrupting the flow a bit too much tho
