Hello Cul de Grace (I assume you are french ? So am I!)
Thanks you so much for this extensive feedback. It is precious to have this kind of return as a beginner :)
As you said, visuals are definitely something hard for me. They are the last thing I've made in this jam, so they are indeed pretty rushed and barebone (not mentioning my complete lack of affinity with any visual art in general). That's a skill I will train along my gamedev journey ! My main priority todaI is first to write a code that works haha. I really want to do everything from the ground up for each jam as much as possible, so that I can learn and improve step by step. This might take a long time, but I hope i'll be able to produce something decent one day, regarding visuals, sounds, gameplay and so on.
Thanks again, I'll try out your game once I can :)
Cheers
