Solid entry. The pixel art was good, and the music and sfx matched will with the style. The UI work was really clean as well.
Its also an interesting take on the standard TD genre. Haven't seen a LR 2D one before. The inclusion of varied stats on diff bots seem to take into account this 2d dimension (e.g. lateral range).
Theres's also no bugs that I encountered. So the feedback would be mainly on my 2cents on gameplay. Firstly, the game is evidently time-sensitive, so at the start of the game (and each round), a start button or a menu-pop up would be a QOL improvement.
To add more strategic depth, perhaps a selector to decide how far laterally the place the bot, would be a better system than LR. This way the player can optimise the placement, adding strategic depth (e.g. placing a tank further, to cater for slots for weaker ranged bots behind the tank.
Great effort overall!
