Really wish I had discovered this earlier so that I could've rated this.
I love how the control transfer mechanic works. It's like a better version of my game. I wish I hadn't made it a platformer.
The puzzles are simple but great. Like the art style.
It does need a few QOL upgrades. It crashes a lot. The diegetic UI is good on paper but the icons that pop up after spacing space interfere with pick up. You don't need that at all. You already sort of show your current modules on your sprite. You just need to make that bigger so that there never any need to press space. You can definitely improve the UX by using the mouse more. as well. Like getting prompts to transfer controls by hovering the mouse over enemies.
The idea to restart by dropping the life module is cute and reminds me off Nier: Automata. But an additional one click restart button would be better for game flow.
If I found this one week ago I would've dropped a perfect 20 rating. Keep going. And I'll be rooting for you.
