Congratulations on your first jam ever!
You made quite a bit of an addicting game here haha
Controls were responsive, I feel like the graphics worked together quite well too! The soundtrack, albeit I liked it, felt a bit out of place for the graphics though!
The different types of enemies, the different types of... "towers", they were unique and interesting and clearly had their own mechanics, which I found very enjoyable!
Keep going and good luck on your future jams! Looking forward to see what you come up with in the next one :D
