nice touhoulike! i got invested in the story in a short run where i died in the first boss, so i tried the infinite lives mode. that felt a bit too inconsequential so i might give another shot to normal mode! good stuff!
a few notes:
- the game screen went black in saffron fight, and did not recover. I could pause the game normally, tho.

- the core attractor sometimes misses, the cores can shoot into wild tangents sometimes lol.

- my personal preference would be to make the collectibles and bullets different-coloured, it's easy to mistake one for the other in the heat of the battle!


Thanks! Glad you enjoyed it!

- I'll have to investigate the issue with the screen going black, it's not an issue I'm aware of. If I find the glitch and push an update, I'll let you know.
- Cores getting flung away like that is actually a game mechanic, it's possible to deliberately fling them back at enemies and blow them up. I worry that the mechanic might be too confusing and I'm tempted to remove it for the sequel.
- I've had this mentioned before, and I've tried resolving it by making the bullets flash, while the cores don't. There's still probably more I can do to differentiate them, and again, it's something I'll look into for the sequel.


Just to follow up, there was indeed a game-breaking issue with the Prism Saffron fight (and a couple of other fights). These have now been fixed as part of the v1.3.4 update and the game should be stable from this point onwards.

great, that was fast! ill give it another go then 👍

The girls in the game were cute.

Do you have an illustration of these girls?

It may be an intentional system, but the character died in the final boss battle for some reason even though it was in Prism Mode.


Sadly, no, I don't have illustrations of them. I'll see if I can throw together some larger-scale pixel art or something to show them in more detail.

And yes, that's intentional. The player can still be hypnotised by the final boss and get a Game Over even if they're playing in Prism Mode. Might be a bit harsh, but I didn't think if it would make sense for the hypno-bullet to do nothing.

Hey, tried to play the browser version of your game but I could not press enter to actually start playing. going up and down in the menu worked fine, just confirming my choices with enter or space did not work for me. Might be just me and my weird keyboard though.

It's Z to confirm menu choices, not Enter or Space. Sorry, I should probably mention that somewhere.


Okay, cool, thanks! Got to play it for a bit and quite enjoyed it, good work!
