Hey Aaron, yeah, I remember you. Glad you like the graphics.
As I'm pushing for time we'll see how far it gets in terms of features but what I'm aiming for is essentially a random treasure hunt with fairly merciless obstacles - 1 hit kill mines and the like. I want to get a feeling of exploration and discovery above all.
"Finishing" each stage requires a set amount of loot, which you have to spend to advance, so "skipping" stages is possible but costly, and unlikely to get you onto the leaderboards. You'll also miss out on pickups (items and health) if you skip stages or dont search thoroughly.
You'll probably be able to spend loot on buying more items and deployables later on, as well as possibly upgrades for your robot, but I want a spelunky-like "start from scratch each time" motif so that'll probably be limited to extra health and boosting your health cap rather than "levelling up".
There will probably be 3-8 biomes with different enemies (3 for starters and expanded later on, most likely), and each will probably include a boss room somewhere in the third stage, which would be followed by a change in biome.
Ideally it'll be both something you can pick up and play for 5 minutes in a coffee break as well as something you can spend a few hours on trying to get deeper and deeper. Maybe you can unlock more robots to play as by doing special things?
Got wallsliding and the core of water done today. Should've got a lot more done but I took on some other work as well <_< Off I go for the day.
