See? It's easy when you're both playing :) Space is like twisting the key in the lock. That's intentional. Glad to hear you had a fun experience! I rather kept it short and fun / second than long and unfinished boring levels, you know?
Cool! Right, simple and good is key for a jam like this. That's what my partner and I focused on (we also made a two player platformer where cooperation is key). And I imagine sticking to that really helped you have time to put in the visual polishes in your game!
Exactly! You get it. My process is simplified to: concept prototyping with simple shape graphics -> mechanics debug & stabilize + graphics "facelift" -> debug/adjustments with 10+ other players' feedbacks. I'll check out Illumin-Mates tomorrow :)
That's more or less what we did, it's a solid system. Except we only had a couple playtesters... that's fantastic you could wrangle up that many! Awesome! Hope you enjoy it!
