Great. This is exactly the scope a first game should have. I’ll second what @artemisia said; add a few more levels and upload to a platform like itch to make it more accessible. That way more people will likely try it out and give you feedback.
Thanks for your advice. I think it’s a great idea and probably the next step to keep moving forward and continue learning. You’ve given me some direction, so thank you!
Because it’s 2D game i’d change controls for UP/DOWN being turning keys and LEFT/RIGHT being movement, other than that game is good for your first project
add more colours, a skill tree, larger map, different vehicles and some automation (belts and bots) and I’m sure you’ll get RCE hooked to do a mindless task for hours.
Where’s all the stuff going once you pushed it into the marked area? Dropping down to the next level to be cleaned up?
