The graphics are really nice on this one! The level environment is cool and well constructed. I really like the time-dilation power, it's a great usage of the theme! I initially didn't realize how important it was fighting the enemies. I do wish it charged a little easy/faster though. Maybe gain some energy back by defeating enemies, rather than returning to electric boxes?
The gameplay is a solid, but could probably use a little polish. Completely understandable in a jam game. It didn't seem like there was any story either, but again, it's a jam game.
I did run into a bug where I was stuck in "attack" pose. I could walk, but couldn't jump or attack. It happened after beating up an enemy who had fallen down from a platform, and was in the air a little bit. I did eventually break free by spamming buttons for a minute.
Overall, I think this is a great demo! I hope you keep working on it!
