And only in this stage. I'm not sure what's causing this exactly (the steam effect...? or possibly the 4-layer parallax scrolling...?). But this doesn't seem right. Anyhow I hope the dev can address this as it went down as low as 3 fps for me and bounced between 3-34 fps the entire level. Being such a technical stage too, makes it nearly unplayable. Otherwise a fantastic shmup though...really had a lot of fun with it...this issue aside....

Runs well on the Steam Deck if anybody wants to know.

It looks like a Raiden II clone! I'd love to see Raiden II or Raiden II DX on Steam someday!

Great shmup 1st off. Very well made! There is a slight input issue though. If you hold down the left arrow an then press the right arrow the ship continues on its path moving left and does not detect the right arrow key press. On the other hand if you hold down the right arrow then press the left arrow the ship will change directions to the left. Both of these input instances need be equal in how they behave....
