nice idea, but the game really needs more tutorial-not  much, just a little more.

Very creative game! Once I understood it it became very addicting. Music was pleasant to listen, fit the game perfectly. The NPC visuals were easy to understand.
I wish the UI was a bit more intuitive, I didn't understand that I could swap the tiles at first, there was no visual feedback, no highlight. Overall good!

The dragging operation on the right might have some delay. I'm not sure if this is due to the design or a bug. But the game is great! The tension from the left tower defense made me need to quickly drag blocks on the right side to attack. The tension from the countdown was fully displayed.

The combo of blocks on the right side would allow me to obtain a lot of colorful blocks at once for defense, which was very satisfying!

I probably felt a bit tired after about six minutes of playing. At the same time, I realized that the invading virus would eliminate the blocks on the right side. It seems that the gray ones are useless, right? Anyway, it was really great!

The mix between matching and placing towers was fun. I think sound effects for placing and matching the anti viruses would increase the feel of the game. Different animations for the different towers would also give them more visual difference. The cable when placing the pieces was a good feature.

I really love a good tower defense game, and this is a seriously awesome idea. I see so much potential in it.

I thought it was really good and creative; I had a lot of fun.

My only complaint is the lack of a menu... it starts right away before you have any idea what's going on, and there’s no reset button—not even at the end.

Also, I didn't notice the enemies getting stronger... I didn't feel any difference after 10 minutes. I lost around the 15-minute mark, though I did neglect the colors a bit, so I'm not sure if I could have played much longer. Plus, there are no rounds or a pause button to take a quick break.

Oh, and I didn't really notice—or pay attention to—the differences between the towers... I just dragged the colors into empty slots regardless of whether they were blue or red... though I did gather that gold is supposed to be a bit stronger.

But overall, it's a really cool game and, in my opinion, genuinely creative. I had fun.

This is really cool! Trying to find the balance between matching and placing is probably the hardest challenge. matching 4 in a row give extra tower is a really nice touch!

I wish there is a visual feedback for holding the piece. It would make the game feels much better.

A very cool game overall I really enjoyed it.

Fun concept!
