Critiktime:
The GameMenu is a very cool idea to make it "part of the Game" - 

In the Game: the movement feels kinda stiff I don t know how to fix that issue 

The Enemies attack from random positions which makes it extraordinary hard to defend against them. 

Please ad a Audio Button/Slider ^^

The indications of "health" of the blocks was a bit difficult at the beginning

How about placing Blocks and turrets and repair on Keys: 1, 2, 3 ?

I understand that the "use WASD and ARROWS" a nice fix for the problem of direction is, but I think it would work to  place in look direction -> would make the controlls a little simpler.

You could add some FX on destroying Blocks, and Enemies.

I didn t understand why the Towers got more expensive when I didn t build any - make the price dependant on the building count - feels more like "you get more you pay more"

The Orange Enemies are stronger, easy visible -> how about making them "slower" but stronger. 

the Attackspeed at the ... 7. wave? was very high and i couldn t defend against them.

If the Enemies can attack diagonal - you should be able to place blocks diagonal I guess... hard to hit them with a block on the head xD was very "good weapon" to place blocks on enemies.

Try to put your VIEW (cam) a little further away so you have a better overfew.

When the Enemies attack at a side you don t see - maybe make an indicator into that direction?

The "day & night" cycle is nice With Wave start and end -> maybe start the "night" when player gets back on the orange Cube? so you have more controll and feel less stressed out.

Last: Make the "cost" and "Moneycoint" better visible. I was confused what numerb belongs to which thing because I didn t understand that the towers get more expansiv when I do not build any. Make an Icon next to it, or give it a Frame in the Center?  just make it OUTSTANDING - and also that it changes -> like  let it  blink when you add coins (just swap color of font from white to black and back to white)

I think you have a very solid Base of a Game that could be extendet very well -> shooting enemies, Stronger Block, Blocks that push enemies around etc. 

keep up the sweet work ! It is a good game!

Awesome game, with awesome gameplay. Though I wish there was a slider for the volume in the options menu, that's my only complaint. All in all, nice job!

this game reminded me of minecraft bedwars, both strategic and fast-paced at times for me! the main menu was a very smart pre-tutorial level. overall, u did a very nice job !

This game is AWESOME!! A really interesting and challenging concept that I actually think has a TON of potential for being fleshed out into a bigger game. Also I LOVE the main menu so much, it's like a mini tutorial! Only real issue is maybe the controls being a little difficult to use, but that may just be me. My best time was 4 minutes I think.

This game is soooo good!! It is very fluid and the main concept is very unique. The art is very good too.

Excellent job!!

Loved the art, animations, and gameplay, but the control scheme felt a little weird, I feel like it might be better if you aim the the direction of the key you last pressed as having to manage WASD, the arrow keys, the space bar, and shift gets to be a bit awkward at times
