Wow, this is a really excellent game! This is one of those games where it's so well developed, that I'm just filled to the brim with ideas on how to improve on the extremely winning formula, rather than just a quiet enjoyment. As such, I'm probably about to brain dump some stuff that went through my head while I was playing, but I don't want it to come across as me complaining or criticizing the game to pieces, this is just me excitedly blathering on about all the possibilities for such an already wonderful game!
Preamble aside...
It seemed like the only /real/ threat was the archers. When I adopted a strategy of conserve "nom" an eliminate archers first, I had a lot more success - but that's also not the most fun way to play. I think the other units need to be more of a threat.
When the projectiles spawn /right/ before I'm about to eat a dude, it feels kinda unfair for the player. I was thinking having some sort of "aura of fear" that prevents attacks from people right next to you might ensure that the player always feels it's their own fault when they die, rather than going "oh that's bullshit"
The "nom" bar running out of steam is important for balance, but also it slightly encourages a more hesitant gameplay pattern - where the player doesn't want to run out of steam and crash and die - so they play a bit more conservatively, however the game is definitely at its best when you're just going NUTS trying to eat dudes. I'm thinking maybe having even more enemy fodder might fix that, since you'll basically always have some juice nearby to keep going, but I'm not 100% sure on that solution.
There's some potential for more spells that the skull head guy could use, rather than just straight up nomming, to try and keep the player super engaged and switching up strategy and playstyle. Maybe an aoe vacuum burst to pull enemies in - leave yourself vulnerable for a moment, but if you land it, you can then perform some high tier nomming.
I feel like I could talk about this game for hours - incredible work. I absolutely love this entry. 5 stars all around.
