I really enjoyed playing this! I love the progression and it feels really nice to play, feels like a procrastination focused version of Ultrakill (well, atleast with the movement and shooting). Movement felt very rewarding and the unique enemies were really fun to encounter, and the power ups felt appropriate for the game. I appreciate the ability to change the keybinds, however I don't think they worked (I changed my slap to a side button and still had to use Q), and I would've liked a crosshair just so I had a better idea of where I was throwing my pens. Also, it heal from the slap felt very underwhelming, and I'd like an EXP bar for some visual feedback (and some music would be nice but I figured that didn't come in due to time)
Overall, really fun game I loved playing it and would to love to play a more polished verison later :D
