I'm not trying to sound like I'm covering up my bad drawing skills :D but yeah, the game kinda gets some inspiration from brackeys with the use of basic shapes and some lighting. I intentionally made the game as simple as I could and let the post-process effects do its thing, which I think turned out pretty well, I also believe adding player animation would have elevated the game even more, but I went too basic with this one and ditched them.
To be honest, I don't really have the chance to playtest for other players, to get some quick thoughts about the game. But I agree that camera panning and signs would have been beneficial to players. And for the checkpoint, I'm debating with myself whether to add it or not, as I feel like maybe the game is too short on having them, but you also pointed out some reasons why the game should have them. As the player's input would always be crucial in making a game a lot better.
Thanks for all the feedback, Steff. That's why I like joining game jams like this, we learn so many things in the process.
