Roguelike snake is a really good idea for a jam game and it incorporates the theme well enough to be considered a fun but short experience. The environmental hazards stopped things from getting boring quick and the dice roll gives you something to keep you going.
I think the biggest issue with it is that the background grid is not properly aligned. Games like Snake work because of how pixel perfect everything is, when you introduce higher res sprites along with a grid where the tiles aren't properly aligned to each cell, it can become quite confusing and disorientating espcially when it matters. I also think (and of course I understand the limited time given in the jam) but a few more features like different levels with permenant environemental hazards or different shapes would have been a nice addition and makes each run unique. This shouldn't be too hard if you look into 2d proc gen.
Overall it was a really enjoyable game and I hope to see it continue development. I think it could be a good chaotic roguelike or incremental game if properly done.
