I've completed your game and here is my feedback.
Problems I found
- I couldn't reach some of the platforms even with Movement speed bonuses
- There is no time warning , maybe have the screen dim like on death
- I don't get the point of replacing hp with hourglass (too confusing)
- I ran out of time frequently in the heat of the battle (because I wouldn't associate hourglass with hp)
- When 2 different bonuses were droped next to each other I only get text for 1 bonus
- Character's meele attack gets boring after a while
- Tutorial is a wall of text , spread them out in the map.
What I liked
- Power up collection is pretty fun (made me kill all enemies i found for drops)
- You have to time your attack so you knock enemies back before they hit you
- Save Point reminds me of Black Desert Online (How could I forget that creepy smile :D )
- Intro music is pretty good
- Character and enemies are well made (I like the fact they change color so I can see they are taking damage)
- The environment is well made, really like the dungeon feel to the game
I enjoyed playing your game but it was frustrating because of the hourglass mechanic, I kept dying because of it even made me want to quit but I stayed on for the ending. If you have time, a story would also be nice at the ending because I expected a little more after completing the game. I didn't get the rewind bit for this jam, what is happening with the hourglass. Definitely need more explanation. All in all good game but a also bit frustrating.
