Thank you so much. Yes, we had more maps, mechanics, enemies and puzzles planned but as this was for the Lost Relic Game Jam, we had a limited time window and ran out of time.
One of the ideas we had was to have a level full of rotating walls / lasers / objects, where a wall would rotate 90 degrees each time you hit it, and this would also cause all other objects to rotate by 90 degrees.
In terms of enemies, we wanted to have even more of a bullet hell feel, with a much bigger variety of bullet spread patterns, to make you move evasively but in different ways. Definitely we can expand on this, and I agree and value your feedback. Is there any other feedback you would like to communicate to the team?
