Good:

• Really ambitious for a solo project to have both PCG and multiplayer. It mostly seems to work, which is very impressive.
• The colour-matching is an interesting mechanic.
• The world feels very open, with lots of explorable directions.
• It controls nicely, and having the double jump available from the start is really useful.

Bad:

• I got stuck in a hole that was too tall to double-jump out of.
• I was confused for a while by the fact that the gun aims in the direction you're moving, so if you aren't moving, it just explodes on you. It would feel better if it defaulted to the direction the character is facing.
• Those sound effects are very harsh, especially the one as you collect an upgrade. They could do with being a bit softer.

Overall, I think it's interesting, and impressive that you made it by yourself, but it could use more polish.

This is a really neat proof of concept. I was delighted to change the seed after winning and see the generator go differently a couple of times.

So, designing generators is obviously very different than hand-designing levels, and while I'm not perfect on either front by any means, I've got a couple design notes:

• It seems like the ending enemies take a long time to find and a fair amount of time/bullets to fight. I think that enemy type was the most fun to fight as well.
• I noticed that I could fall through the fall-through platforms by firing upwards.
• Near the end of my run I actually went looking for enemies out in the 'void' where several of the rings/doors were colliding and that was in some ways more fun than the main corridors. If you decide to expand on this one, an area that generates more like that, with having to find your path, moment (I think it was with seed 1 FWIW) might be worth looking into. (Probably with the rings only temporarily disappearing so you can't softlock yourself.)
• It seemed like the color/bullet system worked pretty well, though I didn't feel like I was moving especially differently it definitely limited my access through the level.
• The sounds had a definite retro charm--my suggestion overall (even not taking part 2) might be to turn them down a bit and grab some music.
• Things do seem a little same-y which in a genre jam like this and considering the experiment seemed ultimately forgivable if still worth noting. It might actually have been worth making maps smaller.
• The ample warp points are very nice both for players getting stuck and players who don't want to walk the whole map.

Overall I enjoyed this one conceptually, and expanded in scope (if lessened in area size) it could be something to watch post-jam!

Good map generation exercice to make a metroidvania map, it’s work good for the generation. Did you have some ressource for map generation ?

Good job.

I think going for a procedural generated map is pretty ambitious, so good job at experimenting with that. I did feel like the camera was pretty spazzy as well. I got to a point in the map where it was just constantly shaking so hard that it hurt my eyes. Good news is that I didn't encounter any spots that made locked in, which is pretty great since it was pcg.

Overall, its a good base to develop further. Congrats on submitting!

I like the concept, but the gameplay was too spazzy for me!
