Game loop is solid that is for sure.
Pixel art is also prettyy cool (I really like the sumbols on the green tiles and main character ofc)

If you make a pixelart game you should stay consistant with it in terms of pixel size in every sprite and all of the UI elements should be in that style (buttons and font are smooth).
Also the UI was not very intuitive, for a long time I didn't know that I can buy upgrades because I thought the next/prev buttons were for towers I will unlock later - So instead of next/prev you could go with named tabs like 'Towers', 'Upgrades' etc.

Game need some more polish like VFX and SFX but the core loop has potential.
Good job!

I like the loop of defending during the night and going out scavenging during the day! I was wondering why I couldn't buy more than a few towers, but I saw you said in a different comment that it was capped at one of each type. In which case I would have liked it better if it was more effective since I quickly got overwhelmed after a few nights xD Good start for your first game, keep up the good work!

Nice! The core loop is fun. I like the character sprite. I like the teleporters. Sometimes buying things didn't work and it wasn't clear why. It also wasn't clear what was damaging some enemies, who showed up with half hp.

Nice gameplay loop, good graphics. A bit hard in the beginning, I wish I had more money so I could try buying everything to figure out which was which. The best in the game was the music, it was a banger of a song and it really fit the game!

To be your first game I think you did an amazing job! I think the upgrades were pretty cool and I like the fact that you need to walk away from your base between phases in order to get resources, that's a very interesting idea that has potential. The music is also nice, and the pixel art of the cauldron in the main menu looks super cool!
