Really fun game! I made a few notes, sorry if you're already working on them, I realise it's an alpha!
Playing on Linux with integrated Radeon GPU:
* Would be cool to have a video on itch.io page; or maybe more gifs; you have lots of cool animations that deserve to be shown off
* Not sure how to use/equip items. Might have missed this in the tutorial though.
* Cool chest open animation!
* Not sure how the number on the element types effects battle. I worked out that it's the surrounding number of the elements that handles the distribution between each though.
* Not sure how to work out which elements have the best effect in battle, though maybe that's intentional like a rogue-like? Maybe if when attacking there was some visual indicator if there is a weak/normal/strong effect at least.
* Half second pause before each attack (on rocks, monters and boulders) and after before explosion shows, this was the biggest issue I think.
