Had to click on a fellow retro space shooter! :) Great opening tutorial and I really like the placement of the ship in-between the A and D. It's super new-player friendly which is so crucial in a game jam. Screen shake was a nice touch, so shooting enemies was satisfying. Pixel art is well done (especially the player ship) and captures the retro style. Would have liked a death screen/transition, and for the tutorial to only appear once when you first start, but I totally understand time constraints. I kept dying on wave 3, but if I had more time to play, I'm curious to know if you implemented unique patterns for the ships. Would be a neat thing to try as an after jam project! Or maybe adding unique special weapons. Anyway, good job!

You should probably add a limitation of missile we can shoot, because by just spamming space bar you kill almost all of them before they arrive, and finish every waves in less than 5 sec!

But it's really fun , i liked it ! good job !
