Heyoo! Thank you so much for taking the time to play the game and write such a detailed review :D!
We can definetly see what you are talking about regarding the Ionian mode, limited testing time surely led to so some unbalances between modes, we already have some ideas to make both modes equally useful and balanced but suggestions are of course always welcome!
We really wanted to imply a more complex system with 3+ modes used in synergy but we knew that with the time limitations it was imposible to develop in time, so it's great you are left wanting more since that's the whole concept!
