Hey Yorkie thanks for your playtest on Level 2, your constructive feedback helped a lot! :)
The sound was readjusted only once but we didn't really have time to fine tune it so it is very loud for now. We'll update it after the jam and add an options menu!
Level design was something we had to work hard for so I'm pretty happy it was effective for you! All the assets were made by our amazing team so they'll be happy to hear that! ^^
The walls were no even textured since we didn't have time to create textures for a tilemap. The easy solution was to generate a polygon and fill it with a color so that's why it looks that way. So I agree it needs a little bit more love!
Thanks for your comment and we'll update the game for sure! :)
