I think this might be one of my favourite games in the jam, if not the favourite. Everything is very well polished, and the gameplay is super fun and addictive,
Honestly my only problems with it is that there wasn't a lot of variety so I got bored around Wave 30, and that it was way too easy to accidentally place a tower in front of you after buying it if you pressed E too quickly.
I think having the mouse visible and allowing you to attack in any direction + place the towers using it would've been perfect.
Otherwise, this game was amazing, and I really hope you extend it out more after the jam!
