Hi Oden...thanks for the feedback.
Yeah I always prefer enemies doing an attack action rather than just damage on contact. And once I add more enemy types and bosses and proper 3d models for them, they'll have better animations.
The progression is limited specifically for this event version. I have more upgrades and power ups planned for the final release version but I'll be adding a few more for the final demo version too. Also will be adding more content and map designs (specifically for the obstacles). But I'll surely look into the games you suggested and also other roguelike and bullet-heaven games.
Also, I added a feature to pause the game and sound when it is not active. ;)
I hope you'll try out the demo version when it is out. It'll have OST by then. :)
Thanks again for trying out our game and for your suggestions. Cheers!
