I love this game! The retro aesthetic, the artwork (which is amazing), the tile system... I really like it!
The downsides I would say: the tile system needs some tweaking, I honestly got stuck quite a few times and that was a bit frustrating. I thought the combat was slow, but once I put the music from soundcloud in the background, it was perfect! The vibe changes completely, I really hope you can implement the SFX and music after the jam because it sounds really good. (and maybe next time implement it as soon as possible ;))
All in all, great work, it has a really strong identity :)
