very nice! i was surprised by the amount of content, this is a pretty fully-fledged tower defense-like. all the visuals are pleasant and consistent, the sound work is great, and i was able to figure out everything i needed to know to play the game from reading the help and messing around in the game myself.
i saw it mentioned in the game description already but it's worth mentioning that i got the bug where an enemy spawns inside of the wall on all of my attempts, which also unfortunately prevents the game from moving forward (your projectiles can't hit the enemies either). but it seems like you guys are fully aware of that and plan to continue working on this past the jam, which is great!
overall i would definitely be looking forward to a more complete version of this. i think the style of the game is already present and makes for a really great jam submission!
