Quite the interesting game! Very fun to play! 

Cool game, shooting precision was a bit off, interesting take on the theme

Altough it was quite easy to get into a "Survive? - No problem!" state, I observed your system a little bit closer and want to appreciate some specific points: 

It seemed that you tried to balance the enemy strength regarding their move speed and spawn rate. At least it seemed so and I like that. 

The idea of fusing dropped materials into traps is great. Especially due to the fact, that I did not had to learn several reciepes by heart. You made a price list and told me, what I have to pay. What I liked very much was the idea of choosing the levels in the first place instead of leveling up after the first build. Maybe a lifetime for the traps, a duration or a number of usages would have make the game a lot more enduring. A lava trap on Lv5 on the enemy spawn instantly lets you win the game. But hey, classic jam issues, don't worry. 

The shooting precision seemed a bit off for me. Did the enemies (specifically the slimes) had smaller hitboxes than their meshes? Or am I just a bad shooter?

Anyway, it was an interesting system and I enjoyed exploring it. Has potential. Good job.

Fun game. I found that shooting enemies at certain angles would make it very hard to hit them. I think making enemy hitboxes slightly larger and making the bullets extra big would make it feel better. Overall, good job!

Very fun, dodging the enemies felt really satisfying, also i think you should change the movement direction so it corresponds with the camera location whilst also making the enemy hitboxes a bit bigger, as that would make the game a bit more enjoyable in my opinion.

projectiles were cool , I was just shooting them randomly lol

Good concept, but the movement and especially the shooting/enemy hit detection just feels really bad. Could be a really fun game with some work, though.

Pretty interesting map building game, graphic is obviously in prototype phase, but it's 3 days jam and core mechanics pretty interesting. Good job! Hope you'll make some updates for the game I wish there was some crispy animations or models.

fun game! i like the concept, but again, maybe some more sounds would have tied it in. also, in playing the game i found the short enemies were a 50/50 shot on killing

The concept is really cool and looking at other images it seems like the room can get really fun. But I found myself confused by the UI and controls, and the bullets sometimes seemingly missed. Otherwise, I think that this game can be even greater with just a few adjustments!

Cool stuff. The lava traps are way too powerful. I reached wave 12 and just stood in a corner watching enemies die the moment they spawn =D

Having some sound effects when enemies get hit and die would make killing and hitting them more satisfying. Other than that the game is really fun. Good job!

This gameplay has great scalability, and I really like the idea. However, it feels a bit counterintuitive that the character's movement direction doesn't correspond to the direction of the buttons. It might be better to perform a coordinate transformation. Sometimes, the bullets don't hit the target I aimed at. Overall, the game has potential, and it would be even more interesting with further optimization.
