Finally, a game from this publisher has been released (again, been a while) you can still enjoy if you aren't a gamerscore chaser though achievement hunters are gonna be cussing a bit on this, lol. I've seen it already.
It's fun like an early 80's type of overly simple gameplay design (with some sounds borrowed from Gonner).
It's very short but for the fun & price, worth it IMO. If you are just here for achievements, there's a guide on YT to finish this in 2 minutes so you can get those & move on if you prefer. The channel for that is OverHyped Gamer, title is Returnal For Poor | Gutwhale Trophy & Achievement Guide.
Combos are your money, get combos by catching your bullet before it touches the floor. You'll need this in shops you reach. You can't point up or down to fire but you do aim down automatically to fire when jump reaches the top of it's height & this makes things tricky but fun. Expect many deaths but restarts fast.
