The selection and activation of cards felt confusing. I spent a lot of time failing because I mostly had to remember a sequence of numbers and that messes with my brain 😅
I think I'd prefer if the abilities had more consistent key bindings (ie zero gravity is always 4 (or something) ) and you gained charges for the abilities instead of them being placed in the first empty slot. My suggestion at least.
But all in all I really enjoyed this game; the mechanics feel polished and the level design makes great use of the abilities you've created. Great work!
