[NOTE: This review is for the game jam version of the game]
The game mechanics are pretty simple: You get a magic staff and it has 3 capabilities: You can float, you can shoot blue projectiles of ... something and you can become small.
The rooms are pretty simple parcour and/or puzzle maps. Only one room has frustrated me a little because the timing of your jump had to be near-perfect, but I still managed to do it. The "shooting" and "become small" abilities work exactly as you think and they work perfectly.
The "floating" ability feels kinda awkward tho. Basically it just deactivates gravity for you for a few seconds, so you have to first jump, then activate the ability and time it VERY precisely. It works, but it's awkward to use. I wish this ability had been more fleshed-out. I would strongly recommend this in case a larger, more serious version of the game is planned.
The game is pretty short. At the end there's a simple but solid boss fight. It crashed but I could restart and finish the game.
The game is okayish but not great. It's well enough executed for a neutral rating. Neutral because the floating is not well balanced and there is one room that was pointlessly frustrating because you needed perfect jump timing. With better polishing and levels, I would have given thumbs up.
PS: My game completion time was 24 minutes, 18.467227 seconds (very precise game timer lol)
I agree that in hindsight the floating ability was not very well implemented; I really should have given the player more control over their flight, perhaps by allowing them to cancel the floating at any time or something.
I also felt that the game was a bit short (I could easily finish it in ~7-8 minutes). I was considering the idea of having more levels after the blue npc's identity was reveled, which would slowly build up to a bossfight at the end, but I kinda ran out of time, so I ended up cutting most of that out and going with a much simpler plot. I guess it's better than nothing lol
And yes, the game timer is far too precise for normal runs (but hey, having a built-in game timer encourages speedrunning, right? :D)
