My feedback for inabox:
What the game does well:
Great execution of the theme 'inside out'. This truly is a puzzle platformer. I never felt rushed to take action and was able to strategize on each level.
I enjoyed trying to figure out the solution to each puzzle. The controls were responsive, and the jump height felt like the right amount/weight.
You also do a great job of teaching the player in the first few levels through UI and level design.
The levels are all in one screen, giving the player all the information they need to complete them.
The art is simple and easy to read. The audio, while not yours, isn't distracting and allows the player to focus.
What the game doesn't do well:
Jumping against a wall pushed my character slightly and killed me because I was right next to some spikes. This is likely due to the way collisions are set up.
The transition from interior/exterior and vice-versa felt really slow.
Areas of Opportunity:
The two mentioned caveats above are things that are fixable. The colors against the background sometimes were a bit difficult to see, but I suppose you can brighten them up a little.
Other than that, well done.
I hope this feedback helps!
