It's a rougelike but instead of permadeath, you just go back in time. Good concept seems like it's getting right along in dev. (Fail and try again.... and again and again. But armed with info.)
My only complaints are that the portraits for the chars when they speak don't match well with the sprites (Maybe some detailed pixel art would fit better)
With the main chars speed+the way she sticks to the ground it almost feels really stiff. I can't really put my finger on it.... kinda robotic in movement. The dodge helps that a bit though once you get it.
Annnd timers.... That might kill this for me. I loved the original 2d metroids (The 3ds are good as well but totally different concept). Used to spend hours and hours searching the levels at leasure, in almost a zen and relaxed state. This feels panicked and a bit rushed in comparison. Thats just me though, I like to take things slow and have time to think. Thus, perma timers (the ones you gotta deal with the whole game) always hurt games more than help em in my opinion.
All in all, Good stuff! I hope the finished game has a way to slow down the timer though.... Maybe somthing along the lines of stabalizers that are hard to find and even harder to activate but add 5 mins to the total timer for eatch run.
