I liked the way you add as many enemies as you want, it's a fun twist to the risk system. I'm just missing some visual feedback on where enemies out of screens are and maybe also some sfx/vfx when they are hit, but overall pretty solid game!

I stopped playing after completing wave 4 because I've went through enough of the enemies and gameplay to say that this was a really fun shooter game. I do feel that the shooting is slightly delayed longer for the player but other than that, the challenge was really rewarding for me.

Various enemies attack in different ways, player can regenerate health if they're not hit for a long period of time, and heck even the upgrade system is working and adds more flavour to the game.

Interesting idea of setting up your own difficulty.  I also noticed that some enemies would spawn a bit tougher than others? That's also a nice risk added. 
Well done!

It's a great take on the theme. You choose your dificulty. that was really fun

Nice game!
I feel like it takes too much time for enemies to come or I have to come to them first?
We also have a wave based arena game if you like to check it out :)

I think harder enemies should drop more biscuits, adding them makes the risk go higher but reward is same as adding easier enemies. Other than that it's a simple game and well fitting for the theme.

I like how you incorporated the theme of risk and reward. The more enemies I fight the higher the rewards. Although the upgrades takes a very long time to see any significant results even if I chose to have a lot of enemies. But when you get there, it does starts to get fun.

Nice game. *thumbs up*

You caught the theme well with ability to set your own difficulty with enemy spawning. I also like the background music. One thing that intrigues me is, how do you get biscuits from these sort of enemies :D. Nice game!

I love the idea of this game! but I do think that it is very easy as long as you don't pick any ranged enemies. Maybe if the game auto picked a few enemies for you to increase the challenge. Other then that, its a good time!

Really like the idea behind choosing the difficulty for money but it leads to the only incentive of increasing the difficulty being time. Still a very nice game and enjoyed it a lot tho!

Really like the "set your on difficulty" aspect, plays with the theme in an interesting way! It's a little annoying to have to kill the 3 skulls in the huge arena everytime you restart but other than that great fun little game!

Loved the idea of the game with this rouge like element. The fact that you as the player could decide how hard you wanted the waves was an amazing idea.

Hitting the enemies could have used a vfx or animation so I know they take damage. Nice submission
