You have about 659,973,991,004,961,200,000 combinations. I tried each one of them, and can say with certainty that they are cool upgrades. This game is done very clean, and I can't really think of too many ways to upgrade this other than making it longer, harder and more complicated. Aka, build a full game. You're definitely on the right track.

This game is amazing and so far it's my favorite game in the jam! I think customizations regarding the jam’s theme don’t just mean changing the player’s look, but also how you’ve integrated them into abilities. I absolutely love the way you’ve implemented it. Every detail, from the scene transitions to the screen shakes when firing, its fantastic especially considering its done in 2 weeks! and i must say if the time given for rounds was even a little more, then things could get real tough becoz those enemies spawn like crazy and i actually just increased their size to max so yeah!!

I love how you need to upgrade both the enemy and player stats! This was a really fun game, I enjoyed it a lot! Hope to see you in Round 2!

Wowwww, Customising the enemy is a nice twist. I instantly regrent my decision after upgrading enemy stats without thinking in round 2.
It is fun, intense also Very well crafted graphics, effects and controls for given timeline.

I really enjoyed this game and all the upgrade options were fun to mess around with.

Addictive and chaotic, a perfect combination of music and mechanics 

The gameplay is really hooking, I like how you must upgrade both player and the enemies! Very nice, I need more.

Quite a fun a game is this aimed to be a vampire survivor like game ? Ohh I also quite like the art .

This was fun, good job!

Making enemies giant is more of a downgrade lol I went fast reload, damage, piercing, multishot

I'm not sure what to recommend, maybe a cosmetic customization or something?

The gameplay felt really satisfying and impactful, and the music was cool too!

This is super cool! I LOVE the trade off, making it so you have to upgrades the enemies too, is super neat! 

Well done, was so fun playing! :D

I loved it, Max the player and enemies almost fully, Good Job, can't wait to see what you do with it next round.

I would appreciate it if you check mine out.

Really loved the idea of enhancing your enemies as well - that's a cool way of dealing with power creep while adding strategy! The art was charming as well. Great job!

Love the slimes, they're cute even though they're the enemies. Interesting take on the customizations but it worked well with the gameplay.
