Hi! How's it going?
First of all, thanks a lot for the demo I really enjoyed it.
Let's talk about your game.
I liked it (Purple Time), the controls are Ok, in my opnion shift+space to jump is a little "too much" to jump, though. Only one key is enough.
Power number "2", oh boy! That power is THE POWER, too strong and doesn't use a lot of "mana"? Seriously make it use more mana. The combat system is pretty good, and easy to understand.
Power number "5" very cool and reminds me a few games where that kind of power are very useful, nice choice there.
Game's layout reminds Dark Souls, very cool and the game is still a demo so I'm not going to talk about the menu I believe that's still in progress.
Conclusion, your ideia is awosome I would love to and play a complete version of the game with a possibility to change my character (I want to play as iron man mixed with firestorm), it'll be nice if you check power number 2 or reduce magic bar so your game will be more survival. Well, that's it, don't give up and keep working on your game I can see it's got potencial. BE CREATIVE!
I can post a gameplay with the link on my YouTube channel if you want but I need your authorization.
