This is really fun. The version i played puts you right into the egg mission which seemed a bit fast to get thrown in, saw an open world thing and tutorial on stream the other day which didn't seem to be in this build which probably addresses that issue already. Might have been a bug or something, after beating the egg mission i got put into another egg mission on the same map and stopped there.
Some feedback: sliding along terrain in the area with the eggs is a little bit inconsistent, sometimes you can slide along it, sometimes you can't, feels a bit jank.
splash radius on the cannon feels a bit inconsistent, but the sniper + cannon + penta loadout i ended up with was a blast to cycle through while killing. I played with wind and the mobility plus crowd control abilities felt very useful and good. The weapon you start with and abilities are very weak compared to the hp of the very first enemies i saw in the egg mission but the damage seems to catch up fast, i had no dps problems after a bit of loot and upgrades.
I got a different spinning 5-pattern weapon which i didn't remember the name for, and it kept shooting out and seemingly getting caught on invisible colliders or something as i flew around. I think my back might have been up against the map edge, and shooting forward away from the map edge the 5 projectile still got caught on it.
it would be nice if the damage numbers against the same enemy combined on nearby hits, the number popups when using the penta projectiles are unreadable when they hit all at the same time.
I like the demo, this is something i think i'd actually buy eventually with more content. I can see this being popular with a pretty wide audience if the rough edges get cleaned up. I thought there was only the egg mission though now reading the other comments there's probably more but i got unlucky.
