Yes, I agree that it lacks depth. There were going to be secondary abilities based on age and would have cost time or flip charges: healing for the young man for time; damage reduction for the middle-aged man for time cost; screen wipe for the old man for a flip charge (though flip charge drops would not drop from enemies defeated in this manner). 

Thanks about the comment about the hourglass and the man getting older on screen. I wanted the timer to have some additional impact on gameplay beyond a game over, so the idea of the character getting older with age came about. The man was originally intended to be a wizard, hence why he becomes stronger with age!

I agree that the lulls between waves is a bit noticable - the gear spawns are on a set timer. I wasn't able to test the balance between the gears and the player, and as there wasn't a method to replenish health, I lowered the damage of the gears and had a longer wave timer to give the player more breathing room. In hindsight, I should have programmed in something that shortens the time between waves when there are zero enemies on the field.

I wasn't able to wrap my head around how the boxcast method was working, so I didn't implement something that depicts the attacks' range for fear that it would be inaccurate (and the deadline was looming and I needed other mechanics).

I didn't have enough time for designing and creating background elements, so it's a little lacking in that department (it's the same thing with the music).

I'm glad you think that the time mechanic was good. I wanted a mechanic that was more involved than the player simply trying to keep their remaining time high - I figured that everyone would use it in some way, shape or form. 

Eventually, I thought of the "stronger with age" angle so that the player would have incentives and tradeoffs to consider when being at different ages. I didn't have time to implement it, but there were going to be additional secondary abilities that would have had different costs (young man had healing by expending time; middle-aged man had a shield for time cost; old man had a screen wipe at the cost of flip charges).

No - it's supposed to spawn a smaller amount of enemies at the start. However, the function that spawns enemies was being called in a loop during setup, which was causing the massive group that appears at the start. I've uploaded a hotfix for this: now the game setup at the beginning will spawn an amount that is consistent with the rest of the game.
