Yeah I was thinking of maybe trying to come back to GWJ every two months or something like that. I also like the Discord server and I think this is probably the best place to help each other as we're all making our games with the same engine. Thanks for your reply, it encourages me towards this option :)
Thanks a lot for the feedback !
I think at least three people (including IRL) told me slow movements were becoming frustrating at some point so I'll think about something. I managed movement with a tween so far (to move exactly 16px each move) but I think I'll look for a way to make a cleaner version of that with a grid system and/or astar. I think I'll spend a few days to research on that and maybe recreate the game from scratch with cleaner code, or replace the player code with a completely new script. What would you advise ?
As for the cow, I also thought I'd add more animals - some friendly, some not so much (like, other grass-eaters are nice, meat-eaters should be avoided). I haven't reflected on their mechanics yet but I have the visual assets and I may take one or two months to make a complete version of this game. I thought I could add several other minigames / hidden mini-levels too.
I think among the jam games/prototypes I made (I started programming last January and jams this Summer) this one is my favorite and... I need to prove to the administration here that game creation is a serious professional project T_T I don't expect to get a super ranking at that point, but people's feedback and advice is precious.
