I played for 52 minutes so i think that says all you need to know. Its a really clever idea to have it as a metroidvania but without upgrades, and its all just knowing how to do something, its a really cool concept and really well put together!
Wow we are honored you played and enjoyed our game that much! Thank you so much :) Btw we are making an even bigger knowledge based metroidvania called Soulchain (it's on Steam), you should check it out, I think you'll like it too ;)
