I think it's an interesting concept, and it would go well with some interesting level designs with different enemy wave patterns and maps that would funnel them in from multiple angles. Really like the sprite work on the mechs and enemies.

A nice we concept that grew on me the more I played. Some simple sound effects and maybe some background music would have added to the feel. It was a bit hard to work out which unit was controlled by which button, clicking on the actual character rather than their button would have been more intuitive.

Awesome sprite work and really cool mechanics!

Fun mix of genres !

I like how you made a tower defense game with a bit of strategy (which having the enemy/units database at hand in games really helps with) and you mixed in some idle game elements (the ressource points increasing auto over time)

And these sprites, especially those gundam inspired mech units are awesome ! I feel that to polish up the overall look the only thing missing would be have some of the UI revamped to match the artstyle  and of course add some sfx and background music, and then you're all set.

My only gripe i'd say is that i didn't really understand the building system, cause when i had 4 units in place i couldn't build any more just move around those i had, and when i had one destroed i couldn't build right away even though i had 100 points so i feel the rules are a bit unclear here :/

Other than that it's a solid entry, and it was fun blasting these space bugs with the giant robot army :)

Cool tower defense game :) I like the little animation of each unity falling to the earth when placed lol. What you have so far is fun and well made, hopefully you can continue with it!

Great work

This was a fun take on a tower defense. I liked the concept of having to move your towers based on the enemy formation. The pixel art was also very nice. Outside of adding sound, the only improvement I can think of would be making the ui for each unit a bit clearer so can know which tower is which and not have to remember them each.

Well done!

It is incredible that all assets are made by you. Very nice art.

Maybe, how to select a unit may be a bit complicated. 

Otherwise very funny and beautiful.
